Well as long as you arent going for the MOSTF, I would say to just get some shivans and warburg nukes.
I would totally join you for an all-blaster STF run, except I'd have to do it on Freedom (or test). Ghost widow should not pose as much of a challenge as you might expect. Try to have a designated 'tank' or two that either already has high defense or packs a trayfull of lucks. You should have your blasters surround the AV from all sides so her AoEs don't get several of you at once, and when someone inevitably drops, just get back up asap (Vengeance would definitely help, but most blasters don't carry it except for very specific builds) and keep firing. If you are not averse to making semi-frequent trips to Ouroboros, just chugging a couple stacks of red/orange/purple inspirations as the situation demands can make a world of difference against tough opposition, like Aeon (even a blaster is difficult to defeat if he's got over 50% defense and 75% res-all).
Additionally, standard practice of dropping half a dozen shivans (ideally fueled by a warburg bio/chem nuke or two) should help to trivialize most AVs.
Rule number six of an empathy defender is NEVER underestimate a blaster's ability to die. I don't care if he has CM, Fort, both RAs, bubbles (both FF and Sonic), and is fighting next to a Storm defender with hurricane on. If there is a way to die in that situation, the blaster will find it.
I am wanting to do an all blaster STF on victory with my Archery/energy blaster the only problems I have is-
1. How to take out Aeon.
and
2. How to take out Ghost Widow?
Anyone got an idea on a good team build/how to take these two AVs out?
