You're looking at it from the point of view of players like Lappe and yourself - who are god among men, so to speak.
Not saying that's necessarily a bad thing - it's kinda nice to have a high skill cap, as long as it rewards that higher ceiling. I'm all for it when I get penalized if *I* placed my shrooms incorrectly. But with our AOE, we get penalized for other people's mistakes - that's something I'd like to see gone. (i.e. tank moves). Or when a boss ability randomly puts a fire patch near your shrooms.
They made resto shroom so much better by making retain its power when you place it again, that's something I'd like to see added for ours too.
Also, I'm holding my reservation on the damage of shrooms overall. 900% AOE burst is going to cause balancing issues for PVP for choke points. I know I'm speaking too soon without actually looking at a numbers pass, but the combo of Shrooms placement -> Starfall -> Astral Storm to Solar -> Sunfall + Shroom Burst dmg (w/ snare) looks to be deadly.
Would love to see numbers from whenever the next round of public testing goes live.
