Just as the title is saying, im wondering which is better or if they are the same thing trying to decide which one to use, i like smash and grab due to how many mobs and the loot that drops.
Definitely not the same. They both have increased mobs, but that seems to be about the only similarity.
Which is better?
I never played Smash N Grab, so cannot really say. That will also depend on what you are interested in.
Grimarillion is mostly about additional masteries, SnG seems to be mostly about faster levelling and more loot drops.
Tbh you will probably also have faster leveling and more loot drops in Grimarillion, just a side effect of having absurd amounts of spawns and heroes…
Though I can’t say which would have MOAR
