TA is the new big deal. They've been advertising it for awhile and it's finally live. The game has probably changed a fair amount since you logged in last. Some vendors have moved and have different items and there is different stuff in the Q and Z store and there are new ways to buy some things and costs for many things have changed and rewards for some common things, like Dailies and Rampages, have changed and there is a new Currency that comes from running TA and you can buy new mods and gear with it and....
Anyway, TA (Teleious Ascendant (sp)) is Rampage tough but only requires 5 people. One thing worth mentioning about it is that it usually takes a long time (hours) to finish the first times due to it is varying levels of hard depending on players current skill, gear, and patience level. That said, I would team with anyone who wanted to try it. Newbie AT, or whoever. Just be 40 and have what You consider to be good gear and toys. If it's your first run I would suggest just going with the flow and learning the ropes and having fun as your first priority and don't even worry about winning. The fanciest superpants in the game on down had to take a long time on their first TA runs and they play a lot more and have a lot better gear than you and me.
I'd be up for other stuff too. TA seemed good due to it's new and relatively big and everyone wants to at least try it and it's only 5 player plus it can be hard to find a spot in a good and/or patient and not screaming/freaking team. I'd been thinking to see if anyone wanted to do Andrith runs since awhile back but I have enough of the new currency to buy severity cores that are about as good as what I could get after cursing about 10 billion Andrith runs. I won't do Dark Speed unless you (whoever) are an expert at farming it. I've had players show me (not in detail) how it's done before and it put to complete and utter shame any attempt I ever made. I'd be up for about anything else.
By the way, I have a special offer on Turbo Grab Runs for your (whoever) newbs for say.... 5g a pop?
