Hi All! I have a level 41 Energy Aura/Energy Melee brute (please, no jokes, I really like her

) who is planning on doing a respec at level 42. I have taken Ghost Widow as my patron and a slew of powers from both sets.
I am asking this wonderful community to help me make my brute more survivable. I realize my powers don't lead to the most "smashtastic" combo, but this is my highest villian and I would really like to get her to level 50.
What can I do? I am looking to beef up my defense/resistance via invention set enhancements and maybe even tough and weave (which I currently don't have). I really want to keep Air Superiority, Fly, Swift, Health & Stamina.
I don't have unlimited funds, but I could save up or craft as I find things. I have about 150 million infamy right now and don't mind being patient on the market/cashing in merits/rolling AE tickets.
My brute is a lot of fun to me since I come from a long line of controllers and blasters. Thank goodness for status protection

! I just want her to be able to survive a bit better. Any slotting or power advice is really appreciated. I guess I'm also looking for specific invention sets that will help these powersets shine to the best of their ability.
All of my shields are 4 slotted (end/3 resistance) and I have all passives 1 slotted. I have plenty of respecs plus dual builds so there is tons of room to play around. I primarily solo, since my boyfriend's villians are all paired with other characters of mine.
Thank you so much, knowledgeable Brute community! I appreciate any help you have to offer
