For me PvP with Grand is only Team. I liked it with giving a RP ball for everyone, its nice help for start of fight. I cant imagine solo
(started to play Grand after nerf EP drain skills).
1.Fountain of Smell... cd could be lower a bit. Same with Defense Breath (cd was 1 min? Really?)
2.Curing Scent - cd is... okay I think. with lower Cd it could be OP in team fights, but yeah range could be better.
3. And again, this poor cast time with long animation...
And remember DBOG probably(?) going to have STR = p. crit Chance.
Grand got personal skill, passive + buff. Crit was useless a bit for him in original DBO becouse of low crit chances + low hit rate.
I think these 3 things are enough for him. He'll be probably rebalanced like other classes - 100 times before official start.
If You have any options i'll be happy to discuss
