Really, Cruzharo, learn how to shut up.
You ask a question in the topic, and you answer it as well. What the hell is your point? Want to know what the ****ing weakest attack is? It's renzoku, damn right, that lame crap attack. I'll gladly enter a server with you, shoot a burning attack in your damned face and you can do a "OMFG L33T RENZOKU!!1111" at me, let's see who takes more damage, eh?
Burning attack owns Renzoku, you know it, you probably can't stand people tossing you around and using that attack at the same time.
