Thank you for the answer.
I think not the “logical” things make devs are “idiots”,No offense.It is a lack of Feedback making things difficult.So actually this thread should be here.Devs won’t be misleading by panel，but player will.Player is where Feedback comes from.Balance cant be done without Feedback.If the miscalculation of DPS formula be fix in 1060，all players will see True ability of the Channeling Skills,I bet some Feedback will change.
Then,I will do a real Feedback rather than report BUG now.
1、The truth is Channeling Skills is brilliant Idear but ruined by Underperforming.
Most important thing is their costs is very high,among all the costs the massive energy cost and can’t move while casting are most pernicious.
Massive energy cost force Channeling Skills prefer end-game skills,you can try to base on a Channeling Skill in low-lvl，then you will know how it feel be interrupted by no energy in every 10s.Players can bear death or failure，but get interrupted will bother them.
Then being a end-game skills the Channeling Skills just losers.Their Damage on the Panel seem equal to those popular end-game skills` real damage （I tested all skills end-game performance），In consideration of their real damage far below the Panel，so I wonder the virtual-high Panel data may misleading players.If the panel is beautiful，but real experience are weak，how they Feedback precisely？How much damage should be buff？Just ”feel“ weak isnt enough.No wonder buff them in evey recent versions.
Channeling Skills do have high costs，so what`s the Reason player choose them?High Reward of course！Which kind of the Reward we want？Damage and special effects of course！I never complain the damage of Bloody Pox,it is design for debuffs not killing.But Channeling Skills is for the damage,I found devs ADD a lot of debuffs to them,it is a good idea.But not means them design for debuffs.because you want to keep the debuffs from Channeling Skills to Enemys，you have to keep Channeling，means you hard to deal damage in other way.Those debuffs work very well,they save cast time from other debuff skills to keep Channeling ,let the Channeling Skills do their real job：Killing.
So Channeling Skill should be killer not loser，their damage need buff badly.This is not for 1% top players,this for the devs and players who love Channeling Skills.A brilliant design should do brilliant work rather than being a make-weight.And the top players just ignore losers.I knew this miscalculation in 1004，but I just ignore the AAR.Now devs made more Channeling Skills,all of them are still Underperforming.If the skills work well why buff them in recent versions？So how about deal this once and for all:after fix the miscalculation of DPS formula in 1060,try to buff their real damage equal to the panel in 1050.
2、Cost and Income
Balance not just about data balancing ，the rich and varied playing method also important.We can accept the high costs of Channeling Skills，that`s their unique feature，But only when their performance is Rewarding.I have said enough for damage,let us talk about special effects.Visual effects of Channeling Skills is brillian,but only work to the Dummy.In real Battle always became a Close-fight，because cant move during the Channeling and they cant kill A powerful monster before it get close with weak damage.So like AAR and Drain Essence you can see nothing but a stupid straightening arm in most of the time.And sound effects also too weak that only can hear the monster.Who wants to use AAR with out Visual effect？
The Close-fight style bring additional cost：high survival pressure.Devs add blood-sucking to Channeling Skill is a good start.But their real problem is sudden death.They cant have proper Viability to face-tank BOSS and massive energy(mage style) at the same time.Who wants to use Channeling Skill only deal with Minions？eg.4 Black Flames provide 28 PR，even Reaper of Lost s pet reduce -28 PR，not to mention the Reaper it self.（My lvl 100 character with 66 PR get 20K Physical damage from Reaper in Normal difficulty）I am tired of BOSSs threat always about reduce resistance.
3、Lightning Tether
Lightning Tether is a genius idea.It dot not need massive energy and you can run during Channeling，like a dream come truth. Problem is damage is too low.I can understand low Costs with less Reward.But its too low to Input skill points.Why 3 Tethers cant tied to The same unit？Then its useless for most BOSS.And 5S is too short！DO You know how hard and BAD its feels to tied 3 Different unit in 5s during runing?In fact it only work in Close-fight，and just for assistant.If I need assistant in Close-fight any skill of INQUISITOR can do better than Lightning Tether.I afraid of this game only have one way：face-tank.
I know its hard to keep Balance between Close-fight and H&R.What make H&R work will is going to make Close-fight go OP.IF Just give massive damage to Lightning Tether,Close-fight style will still be the bigest winner.
So why not change the Storm BOX to a summoned creature just like Wind Devil,with more move speed and last more than 5s of course.A Lightning Tether always tied to a Storm BOX with sommoned limit.It will solve the problems like：how to deal full damage with a single BOSS,how to click precisely on 3 Different unit In 5s during runing, how to keep the distance between player and missive monsters,AOE is Underperforming by the main target been killed too early.With out those problems the Player is free to run,even with low damage the Lightning Tether can do brilliant assistant to H&R style in this way,and Close-fight style have the same single damage but smaller AOE Range.
