I may be a small minority but i think angel of light is a perk with a lot of potential but often executed poorly. I like to use it with my fusion rifles w/ icarus to give myself an aerial advantage. Kind of gimicky but when done right it has a high percentage of success. My biggest critique to the perk is that it is held back by how it's activated. ADS before centering screen on a target is sluggish and disorienting by itself. Now try doing that mid air and it's plain frustrating. I think it would be nice a gesture and a fair adjustment to have angel of light activated like an evade (B, B or O, O) giving time to center the screen then ADS. I know i may be catering to the claw users and people with elite controllers but this perk is under used and could use tweaking one way or another.
Sounds more difficult to me but I see where you going. Sometimes I don't want to hover when I ADS in the air but it's become natural, I think two clicks would make it feel bulky. I think adding allot more AA and/or Icarus and maybe a little more float time would make this perk amazing. I don't mean to make it a viable sniper perch or a broken move used with any ohk special. I use it allot with a sidearm but when I try it with my scout (tlaloc) it's extremely difficult to line up a shot and fire 4 or 5 shots before I start falling and at that point I can't finish off crap because my gun starts shooting all over the place. Can't tell you how many times I've missed the kill by one shot when I fired 5 times dead on but I was falling.
