Xenomorph is fun to play against

I hate to play against Xeno and Singularity. Xeno is really strong and Singularity is just boring

He's more fun to play as than against to me, which is why i've been maining him in recent time, hitting Survivors with the tail feels satisfying, especially when it's a corner hit.

Also Wall Climbing would make Xeno's power really map dependant and facehugger would not have a proper way to be implemented, unless of course you just want a recycling of pig's reverse beartrap mechanic.

I'd rather have acid blood pallet breaking be part of the iri addon than basekit.

Also the queen uses her tail in Aliens, not to mention that if the AVP game (which many say actually feels like you playing as a Xenomorph) can have Xeno use it's tail as part of it's attacks, then there's no reason why dbd can't as well.

Xeno isn't really fun to go against.

While I agree that Alien's kit is underwhelming, you have to reign in your expectations when it comes to DbD. Most of the abilities are simple and derivative of one another. Many of them are some sort of dash or ranged hit. They gave freaking Nemesis a whip. Expect simple, limited ability kits because BHVR is not able to program anything more sophisticated, at least not with the 3-months chapter cycle. Something like a wall-climbing ability is so far out of the realm of possibilities it's comical (much as I wish it wasn't ... although I suppose Singularity's biopods actually do kind of set a technical precedent or fundament upon which such a climbing ability could function).

I disagree with the idea that Xeno is fun to play against. A competent Xeno will basically never get pulled out of power by a turret. With the resistance add-on, not even by two turrets. That isn't fun, it's frustrating that turrets don't do anything but briefly slow Xeno down. Particularly because the tail attack is oppressive and all but guarantees hits at most of any tile.

Playing as Xeno isn't as satisfying as it could be because slapping turrets is a chore and the tail attack is not very intuitive at all. Better visual feedback as to what actually happens with the attack would be nice, for one thing. But Xeno is still a very lethal killer, get good at using the tail attack and you will wipe up most groups you get. You can also get ambush hits on surivors when you come out of tunnels, plus with the 24m terror radius in crawling stance and custom terror radius audio, you can definitely get the jump on people, particularly if you use Monitor & Abuse. The map traversal and tracking potential also isn't bad.

My wish for a rebalancing approach to the killer would be to buff turrets and Xeno at the same time. Make the crawling stance even more menacing (such as by increasing the range of the tail attack, or being able to destroy pallets and walls with it) and/or make the bipedal stance less unmenacing (such as by increasing its movement speed), but also make turrets more impactful and harder to play around (such as by making it so you can't destroy them with your tail, and the fire actively slows you down, multiple turrets should stack again, nerf the resistance add-on). An Alien gameplay loop more revolving around placing and playing around turrets and retreating into tunnels to recharge ability after having been forced to destroy a turret seems much more unique and fitting.
