Ok look.
Crane has few abilities that boost their surval quite alot.
First is crane discharge, wich boost their CON by 26
Second is put out the flames, wich can heal 4k+ if upgraded sub weapon everytime.
Cranes have also ability to slow + few movement speed reduction skills, to keep their oponents wich dont have 35m range skills, at at a nice distance.
And there is also the sleeping skill.
Cooldown of sleep is 42 seconds, and duration is 23 seconds.
If you go use alot of cooldown reduction, you could litterally just spam sleep , then debuffs, slow + Kd and sleep again into a endless circle
Throw in a few dots and burns and let them die in their sleep.
The main problem cranes have against classes that can dish out alot of dmg early on.
However if crane hermit player aquires alot of defences, con, and just be tanky enough to outlive that first momentum, it will become almost impossible for other classes to defeat crane.
And once you have crane player, who is tanky enough, and knows how to pvp other classes perfectly, he will defeat (almost) any class in 1vs1.
Sure i understand why you want a the stun being on Double gut buster, because that skill doesnt wake up the enemy in their sleep.
I dont even think that the idea is bad , it would save the trouble for cranes to sacrifise skill points to reach the poison skill, plus it would work on enemies in their sleep.
That suggestion would change
1. save alot SP (dont need poison anymore)
2. can use it on enemies in their sleep, so u can stun them as soon they wake up , or just incase u wnna keep them at a distance and u worried they stun u before u can cast sleep.
3. pretty fast animation too.
4. will help you fight SK easier
downsides
1. wont change a thing against karma
2. in my opinion, a buff thats not really needed
why? because in my opinion, there need some rework in PvP on both karma and SK first, and after that, look how situation changes and then look at other classes. not buff one because other classes are obviously OP.
