19 Alts/10 lvl 50s (3 Tanks, 1 Controller, 1 Sent, 1 Dom, 1 Brute, 1 Blaster, 1 Stalker, 1 MM)
Only one is T4 incarnate x6 (77 Veteran Levels, last I checked)
Half of the remaining are at least +3 lvl shifted
the rest have at least Alpha t3 (+1 lvl shifted)
All these level 50 incarnates, you'd think I'd join a TinPex but have never done one.
Of the remaining 9, 1 (a second MM),I am for sure taking to 50, 1 Corruptor and one Defender who will probably never reach 50. The rest are just to join low level teams to help.
What my play experience tells me. I enjoy teaming at low levels much more that post 50. Once I get to a certain point, I just do it myself. However, I can count on one hand the number of DFB I have done. I don't do many TF's. I always join in on Giant Monster kills though. More for the badge than for the Merits.
