If you like Action RPG and Warhammer 40k then this is the game for you. This is the game Warhammer fans have been looking for.
Pros:
Achievements actually do something, you unlock extra points and more features.
Multiple talent trees that unlock through your play style with great customization.
Fantastic story with interesting elements, like controlling an Imperial Knight.
3 Classes with 3 Subclasses each + more through expansion.
Crafting, End game campaigns, Hidden missions, Daily and weekly quests, guilds and lots of end game content.
Staying pretty true to the Warhammer universe.
Affordable MTX and Downloadable Content.
Cons:
The only way of trading is trough sending items with post directly to another player, no public trade channel or such.
A few bugs, allocating passive points sometimes mess with your character, laying mines near objective makes it un-clickable, etc.
No Necrons, Tau or Orks
