Yeah, I've been buying about 2 a week on my main currently. I have like 0 luck in-game so I'm not holding my breath. I've heard most will go for gold cap which would be nice since I'd blow it all on transferring my toons and roomates to a better server (Curse Blizzard for believing package deals are bad).
That would be nice, since it's easy to forget some, plus I hate having to port just to the Antoran Waste's Vindicaar just to get that one. Plus sometimes just traveling out to get them specifically makes me not want to go get them lol.
If you are doing AP then that explains most of it. I can definitely understand why some would do them. Right now I'm just letting AK stack so I get more AP per resource as I'm not in any rush to hit cap.
Champion Armaments though I would imagine you'd be at the "cap" of what you need in terms of having a surplus of each new piece. I think I'm about ready to remove my +20-30% +8hr tokens with +Spell/Hazard/Minion so it's more of an "always on" boost since with my two mission reducers can knock it to below 8 hrs pretty frequently. The +50% pieces are pretty nice.
