no problem and the games progressing at a steady rate. When I started playing the level cap was much lower, about 16 I think, and new stuff kept coming out like pvp, ladder pvp, big boss called minotaur nest that you can look up on youtube. Then cap went up to 32 and loads of new content and dungeons, gear and some additional pvp modes to go along with it . I bet if you start playing now by the time you get to 32 there will be a level cap increase up to the 40's somewhere.
Forgot to mention the variety of classes. 4 classes to choose from and each of these classes can pick out of 2 professions to go into. For example if you choose the sorceress class you get the option of either becoming an elementalist who specialises in the elements fire and ice attacks or a mystic who has dark attacks such gravity pulls, dark missile things, time-stop and long distance teleports.
The skill trees are quite complicated too and requires careful planning, everyone seems to have a unique build. You can choose to specialise in 1 area such as only upgrade into the ice side of the tree as an elementalist and not pick many fire skills so that enemies are frozen and slowed for longer durations and with a bit more damage, or focus on the fire side to maximise damage but not have so many disables, or I see a lot of people making up a hybrid build, a bit of everything so although their damage is a lot lower they have a wider variety of attacks and combos.
