Bit late to this thread - will probably plat this eventually.
Cant say I personally hunt for the plat, the trophies more or less happen eventually just playing the game (a lot),
I Think theres just two trophies missing now
My last class to 70 - Monk - is only lvl 45 or so and need to do more bounties (havent checked how many completed)
Usually I play it together with my gf and whoever on friends list thats online (not so often nowadays, most moved on to other games). Heard theres lots of cheating in this game but never seen it myself since I typically dont play with strangers.
I must say I really cant explain why this game is so fun to play, but somehow it still is.
