I doubt they will make you aloud to go past level 60.. There's a total of 51 talent points, which can give you upgraded skills and such.. (Not really going to explain it) but, if you can reach the end of the talent tree, like in DiabloII.. Usually you put 31 points in a tree to get the special power. There's a total of 3 talent tree's you can go down. Anyway, they made only 51 talents to prevent you from getting too many talent skills.. For example the mage: 21 in arcane can get you:
Evocation - 1500% mana regeneration for 8 seconds..
Presence of Mind - All spells below 10 second cast time are instant..
And then you can put 30 into fire if you wanted fire power.. Or you can just spill them into arcane or ice.. But, they made only 51, because if you had 52 you could get those two skills ^^ plus Combustion (31 points in Fire) which does 100% next fire spell is a critical hit.. Presence of Mind + Combustion + Pyroblast = instant 1500+ damage, which is basically an instant killer in PvP.
