Please allow items to give bonuses to 3 skills/3 masteries as opposed to just 2.
This opens up a lot more potential for balancing items.
Allowing an item to give bonuses to three different skills could allow you to pump up a wider variety the weaker more passive skills of two classes instead of giving significant bonuses to just two skills.
You could also give a bonus, let’s say +1, to a skill from 3 different masteries, allowing an item to fit 3 class masteries instead of just two.
This will be especially relevant as more classes are released, as it’ll allow for items to be designed with a few class combos in mind instead of just a single class combo. Making an item give +1 to all skills in 3 classes will suddenly make it especially appeal to 3 dual class combos instead of just one.
This may seem OP (ofc you can just give it low other stats) but you could also use this to make a 5 piece set fit more classes. You could even give it’s individual slots a small amount of +skills to 3 classes instead of 2. It just opens up a lot of stuff.
This may not be signficant now that GD only has 6 masteries, but for modders who are serious about adding new content it’ll be quite the boon. And for future expansion packs I think it’ll be something nice to play with as well.
