I've been waiting for 1 on AH for a while, but I think I'm going with Flame Pearl cuz I'm not really sure 1 extra Str is worth 5.5M extra. Not hating on the crafters for selling it that high tho, it's prolly very hard to HQ it. Guessing synergy is still only 80 cap atm, but once it gets to 100 or 110 this will be much easier to HQ. Think I'll buy 1 at that time because price will likely drop to around 2-3M. Just my .02.
Well look at the big picture... If you could have 1 more str per slot that would be 16 more str. That's quite a bit of str... 1 may not be worth it but in the end is 16? You decide...
