I have issues with a some of my characters. They disconnect the game fairly often for everyone in that game.
For example my nova sorceress: When I do nova in 1 player game, there is no problem. But when I join games with a lot of people my fast cast (105% fcr) disconnects the game if I keep casting nova. So I have to take breaks in casting which is dangerous for my hardcore sorceress.
My warcry barbarian has the same problem.
When I try different build (fire ball for example) this problem doesn't occur.
It seems that skills that do damage in a circle like nova and war cry have this issue.
I really love the skill nova, but because I mess up games people don't like to see me coming, or they ask me to do static field all the time. Baalrunning is already boring. When I am not allowed to use my main skill it's even more boring.
Going for 63% fcr is not an option. these skills really need at least 105% fcr to be effective.
My Javazon disconnects because of lightning fury. I respec to bow. I disconnect because of strafe. I create a sorc. I disconnect because of nova. I make a singer barb: war cry disconnects. Lets make a zealer then! Zeal disconnects because of torch proc.
