welcome lads, ty for reading and this is little sugestion i got for you and that would be ability perks. lets just simply call them.. PERKS

so whole idea is to add a litle "class" customisation to the players. perks is a ability you can unlock and chose from, and get bonuses from it.

lets say.. a guardian, who plays them? wery few.. choseing a guardian perk would award your shield whit 50% resistance. meaning it only takes half dmg then usual and its lot more durable, it would give guardian more fealing like he is a tough guy and all that.. the perks can be lvled up wich will make them stronger. works same as heat but only up to lvl 5. there would be many other perks, here are some my ideas but fell free to post your own.

iron wall -gives 30% shield durability +5%/lvl
eagle eye- gives 20% longer range on guns +5%/lvl
kataklisam- increases the bomb range by 10% +2%/lvl
critical hit- gives 3% chanse of cuseing double dmg whit swords +0.5%/lvl (dont attack me coz DA and GF are owerpowered)

alchemist- increses the status efect chanse by 30% +5%/lvl
bloodlust- upon killing the enemy the player has a chanse of restoring little of his own hp. increased chanse whiting each lvl.
powerstorage- each attack made by same dmg type makes player slightly more resistant to that same attack. stacks up depending on lvl.
sight into ambys..- upon death player will cuse masive normal dmg to all ennemy is his close range. range and dmg increases whiting lvl

so yeah thise are some of the ideas, the perks would be aquiered from boss tokens altho they would be rather expencive.
im sure you will all say that the upcomming pets have the simular role but this is my opinion, i think this would be intresting. also sory for a terrible spelling.
