I am very excited for these buffs! Lex Luthor has been my main since the beginning & has helped me get to the top 600 players world-wide on the leaderboards, even without the update (despite the fact that many of you are likely higher on the leaderboards, it's something I am incredibly & personally proud of) - in any case, here's a list of my musings on the subject...
Lex Probe: I don't know if it would be unblockable, have better tracking, or maybe both - regardless, I'm extremely happy with it.
Lance Blast: I actually use Lance Blast quite a bit, particularly after hard knockdowns from a distance - the added damage is going to be a definite boon (see what I did there). The lvl. 2 & 3 versions, if timed correctly, will be great for destroying aggressive players if they're at a distance & charge in (now if only it broke through armor with a lvl. 3 charge).
Super (Coordinates Received): It's nice to hear that Aquaman can't cancel the Super with his trait anymore, because it really is a bummer to have that happen & waste all of that meter. Someone mentioned that his super should grab you much Like Sonya's X-Ray does in Mortal Kombat (that is to say, if it hits you, you'd get hit by every single following hit); I'd like that - It would really add to many of his combo strings.
Also on a side note about meter & his Super, I've never really felt a need to MB any of his moves. His Orbital Strike still knocks people down & is virtually unavoidable after a hit or block with a Lex Probe (& even allows for trait or another Lex Probe) without the MB (although the added damage is certainly nice; I also could never seem to set it up so I could get a combo off the bounce either - you guys are more than welcome to show me how to do this). His MB Lex Probe knocks opponents down making it hard to combo with so that's not really worth it, & neither is his MB Gravity Mine unless you're up close to combo off of the bounce. I usually save my meter for the Super & it has saved my life on numerous occasions against overly-aggressive players who attempt to move in for the kill.
Gravity Pull: I wish it would stun the victim for slightly longer. I find certain combos hard to chain into it such as his B2U1D1 combo.
Corp Charge: As fast as this move comes out & as good as it is as a wake-up, I think this move is perfectly balanced; the only thing I would change, if anything, is to make the Air Corp Charge safer upon landing - this would give Lex more options to close the distance safely.
Trait (Energy Shield): Out of curiosity, I wanted to ask - would you guys be willing to get rid of lvl. 1 & 2 trait for an instant lvl. 3 trait if it meant for a slightly longer cool-down time or do you prefer the way it is now with more options available to you?
