i havent met many people from the Justice server personally, so this list is small.
XL5: the craziest player ive ever met, fire/energy blaster during i4, he charged everything and kept me on my toes as a grav/emp troller. Showed me how to keep everyone alive if i was the only troller/def/buffer on team. Showed me that i loved controllering, locking down enimies and buffing allies to keep the battle, keep people alive and enimies helpless. (never been a fan of doin damage, prolly why i cant stick with a blaster past lvl 6, but i got a scrapper to 50, im not a complete lost cause

)
Matt Mavio: RL friend of mine for a long time, got me into the game and got me into his sg when i started, the same sg im still in, now im leadership, and ive seen alot of friend go, and new ones show up.
Nanoflex, Amaraa, RockMason, Soothing Touch, Protector, and the rest of my SG's original leaders, who would let me tag along when XL5 left due to ED, learned the joys of SO in the mid 30s, what a difference.
and the rest i learned from pugging and reading forum posts on char builds and concepts, its been a good, long ride.
