1. There shouldn't be a specific stat bonus, remove that bonus or just apply the bonus to all the stats.
Just an example, Giont (Kruxena PB), increase MIND/STR/DEX.
What the hell a soul hunter does with that STR/DEX bonus? And mind is a pretty poor stat for a soul hunter...
2. Players should have an "hidden" 50% resistance to Possession Beast Damage, since there are players that can hit 10k+ with it on anything.
And that's really boring that a team loses a battlefield, because a +30 used Possession Beast and 2 hitting everyone...but the damage is ok in pve.
3. Balance Possession Beast skills range/damage and effects.
Just an example, Giont level 80 skill "Increase party member Short Range Physical Attack Power by 94".
Again, what the hell a soul hunter does with physical attack power? and 94 is a joke at 80+!
Atm, Rufus is the strongest PB, while Giont is the weakest (because low range attacks/damage, bugged castings, useless buff, fail stats, etc..)
4. Limit the Possession Beast in Battlefield.
Anyone can enter in battlefield with full hardcore gauges and 2 hit everyone for a lot of time. When a temperion enter battlefield, the HC gauge should reset to 0%, that would fix the problem.
