I've read something around, can't remember where, about a dungeon encounter where you fight waves of mobs while protecting a relic at the center of the room, and you can use objects in the scene to help...
is that true?
uhuhuhuhuhuhu... that is good...
Leiloni, I truly hope that you're a girl, cuz every time you post after me, you bring a smile to my face. And if you're a guy this'll be extremely awkward. LOL.
ROFL yes I'm a girl. :P I've been told my posting style reflects that anyway.
Really had to ask this? yes they will have mechanics you have to pay attention too like every other game weather an FPS shooter, an RPG like Skyrim, or even an MMORPG; albeit while TERA IS an MMORPG it is NOT WoW, Rift or Aion - it is it's own game - Treat it as such. Comparing the game to other games can only mean you're looking for things to make or break your decisions without playing it begin with.
Acquiring an anwser to a question such as this one is better accomplished by watching videos of the CBT weekends from different class views and reading up on the mechanics of the game such as patch notes.
TLDR; MMORPG's BAM/Bosses/etc all have a strategy to them some more than others, and like before you should read up and watch videos - there are no addons to help you.
