i leveled balance until around 32ish and switched to infil, but the difference in game play is noticeable, it went from a good constant damage class with good killing power but lacking in burst, to probably one of the funnest classes ive ever played in any game. i do think that they should add a bit more into the stealth and break the norm on the usual's (ie. after you break stealth increased force regen) but other then that im loving it and highly suggest it for pvp and leveling!
