Psi melee or Kinetic melee stalker with energy aura, invulnerability or super reflexes secondary could be good. Would solo really well and scout stuff for teams if they want it (don’t forget to get Assemble the Team from the START vendor). You could pick up Psi Mastery epic to add to the theme. Hover in the flight pool is reasonably speedy in missions and has good close manoeuvre control.

Sell your big inspirations on the auction house. Some of them go for upwards of 50 thousand. You can get them from the P2W Inner Inspiration free power.

if you like to play lots of Alternate characters I found a great way to save Inf is to make a personal Supergroup and invite all your Alts with /altinvite characters name then make a base with storage racks for IOs and invention salvage plus a crafting station. you can now put your lower level IOs in storage for new Alt characters when you do a respec.

I would be interested in a new Archetype that uses dominator assault sets as their primary and support sets as their secondary. Probably with a break free clicky as their inherent ability and defender ancillary power sets. A Vanguard EAT might be fun too.

How about giving Heal Other the ability to affect an enemy with a -regen and/or -resist debuff? That way if the team is not being injured the Empath can make a contribution vs a tough opponent. I kind of think Empathy and probably Force Field could be given a slight boost in the debuff department to make them a bit less situational.

I had some issues too, in the end I picked up tough and weave and hasten, dropped the siphon attack. I use the first two attacks from Rad with the quick animations and the last AoE. The other attacks I found took to long animating for my taste on a brute. I also picked up Darkest Night from Ghost Widow pool and it has made a huge improvement, gloom is also pretty sweet.
