GAR - I had fun actually spent a few days doing nothing but that instead of leveling my characters.
The good - Had fun, was a nice different diversion, there were helpful players who helped me get through the content. Communication, knowing that it was coming relatively soon and when it was ending really helped.
The bad - was pretty short, with the amount of time available it was very hard to earn enough credits especially when I only had one toon that was able to run the event. So I spent almost 250k to buy tokens to get the weapons I wanted. Which meant that I know have to start earning some more money just so I can may the outrageous cost to pull out the mods.
Rakghoul Plague - Communication COmmunication, Didnt know it had started, and then thought it was only a lvl 50 event.
Other note - of these come more frequently then I have no problem with the limited amount of rewards, if not shame on you.
