To second Jbeezy, shes very very strong. Vatista/Es is an incredible team as well. Like threat-to-anyone strong. I dont main Vatista, but I do play her, as she's one of my "I cant friggen decide" characters. She's a stroonnng zoner with some fun stuff. Her assists are good, and she makes use of a wide variety of assists herself, so chances are good anyone you pair her with will have at least some synergy. She's also a powerful control character, she can really lock the pace down and slow a match if she wants and her neutral control is very strong. Her being a UNIEL character also means she can reverse-beat (let me know if you arent sure what this is) so her stagger, poke and blockstring game is stronger than a lot of characters. She's not a mix character though.. Of course, everyone *has* mix in BBTag, but she isnt particularly strong in this regard. If you're interested, @ me and I'll record a couple quick vids showing her zoning and projectile potential with TK orbs and such.
I main Es. Es can zone with her projectiles to some degree, and her normals are batshit. She can use her Crescent Arts moves (the ones where the sword leaves a trail behind that after a moment pops, hitting again) to control a lot of the space around her, while firing off projectiles. She's not a dedicated zoner, but more of a control (neutral, space and pace) and mix character, with enormous damage. Really though, she's sort of like BBTag's own version of Cell (she's not the only character that warrants that comparison though), as she does absolutely everything. She has strong oki with her J.C stuff, and she can pressure extremely well. She does absolutely everything. I personally think she's in the running for best character in the game right now. People make the mistake of thinking her mix is her 214.A and B moves, but she's a lot more nuanced and a lot safer on her mix than using those moves exclusively. She can instant OH and combo via assist from a range *no one* see's coming.. Her assists are excellent and she's not *toooo* picky on what assists she wants/can make use of.
Additional character to consider - Rachel. Have you looked in to her? If you like zoning.. mmaannnnnnnnnnnnnnnnn. You were a Deadshot main right? She has some similarities to Deadshot. I know you wouldnt think that, but she has a similar zoning style, where you're putting a lot of projectiles on the screen and trying to bullet-hell the opponent, and when you are in close and personal, Rachel has a *very* strong 50/50, pressure and stagger game. Additionally she's a trap and setup character on top of it all. She has relatively low combo damage, but its not pathetically low. Again, if interested, let me know and I'll make a video for you.
Hyde and Gord will pair up just fine with Vatista. Hyde in particular is extremely strong. Gord is as well of course, but honestly, he's a diminishing returns type character. He will just mow down opponents who dont know how to deal with him, but vs really solid players he's still totally viable, but he's not as solid as Hyde or Es would be, imo. He is still really strong, and really nasty - but I feel like he's (just speaking in generalities) more of an A tier character vs the S tier of Es and probably Hyde. I'll be honest though, I dont know a lot about Hyde myself. I'm calling him super strong because that's what Ive heard from several sources, but I dont have personal knowledge of that.
@JBeezYBabY Ok, I need to apologize and make a retraction about something I said in my recommendations post after watching your sets. I criticized your use of Vatista's lasers, and Ive come to realize that I was partially wrong. Some of what I said, I still stand by regarding orbs being strong tools and lasers being dangerous, BUT, depending on the MU, it's actually a lot safer than I realized to use them from halfscreen + range, and they are a stronger 'just do it' zoning tool than I gave them credit for.
