What a stupid rant. Yeah, by all means, lets nerf the game beyond all recognition to cater to lower levels. FYI, you're only 1-49 for little while. 50 is permanent. Suck it up and level through it.
I've been playing in warzones with an assassin and marauder and having a blast. Sure, I get stomped by a mob from the other team, but it happens, that's pvp. Pick and choose your fights with more discretion, and communicate with your team. It's works even in a pug.
And one last note, the classes are not meant to be perfectly balanced, not going to happen ever. MMORPG class balance is a pipe dream, wake up and get over it. Know your class, and learn it's strengths and weakness vs the other classes, and play accordingly.
