My main is a tanker on Torchbearer, who was previously my main on Freedom, who is 50+1. I have a couple of LoTg's, a Miracle +End, Numina's +End/+Heal, and a couple other special IO's on this character. I have a couple of set IO's frankenslotted, but no set bonuses.
I have another 46 alts on the rest of the servers. None of which are level 50. I don't farm. I have no issues with people who do, it just isn't fun for me. I've also never done an incarnate trial. I'd like to try it some day, but I doubt anyone would want to carry someone like me who doesn't have any idea how they work.
I don't know if I'm the "target demographic" for the devs or if those of you who have a dozen "soft-capped blasters" are. Either way you now know my perspective.
I think the vet levels are great as they are. I don't think anything needs to be added to or removed from them.
If the devs added the option to set the difficulty above +4 for level 50s (or for anyone) and/or the ability to raise it above 8 players, I think that'd be fine. Let BillZBubba solo missions set on +8/14 players if that makes him happy. I'd never do it, but I think that more options are better. I'll stick with my +1/+2 levels and/or +1/2 players.
