People, educate yourselves on level and gear scaling in BGs. If you enter a BG at level 16, all your non-BoA's will scale up 3 item levels while in a BG, and your BoA's will scale up to their level 19 stats.
No one has tested cloth gear on a 16 yet, so far as I know. I imagine that the sun belt will scale to 6/6/6, serpent gloves
should scale to 7int 5sta, and otherwise I have no clue.
Nollix, you will most likely end up with better stats on a 16 mage. The scaling should be in your favor, as long as you use Walking Boots or the hit ones.
http://www.twinkinfo.com/forums/f43/bends-friends-gear-scaling-index-guide-49230/ from the f2p forum is a good reference, though since they are 4 levels below their bracket's max, their gear scales up 4 item levels rather than the 3 yours would.
