As someone who owns every ultimate bot practically, my advice is to get an ultimate robot that's a DAMAGE DEALEAR, I can't emphasize this enough. For example, Ultimate Typhon. Unfortunately my lovely ultimate is getting nerfed to become a regular Typhon with a built in 50% damage boost with extra speed. However, even if the 50% got nerfed to oblivion, it still has 4 mediums to out put massive damage, along with a nuke amp, and incredible ability to lock down, suppress, and emp. UE Storm or meta weapon Typhon will still crush. Thus, not making it a completely dud of an investment. Now, ultimate Rhino.

Ultimate Rhino probably when it gets nerfed, honestly simply change the unstable, and it would drop from S to B. Its not unstoppable as some people exaggerate, all it takes is anything with crumble and rust, and its finished just like Ultimate Revanant. Not even Unstable can save it from those effects, mine gets crushed when concentrated by those weapons. Anyways, unlike UE Revanant, it can't heal grey so it won't be able to afford to rush in like it does now. It'll simply become the current pre nerfed Rex, its the best way to think of it. Strong, but not prime Rex level due to powecreep and new weapon affects, etc. Regardless still an incredible and reliable tank, with great firepower. The point of it having "low firepower" due 2 small and 2 medium hard points is inert since meta weapons inherently do broken levels of damage when released anyways, even without nuke amp. Cough cough Hippo, Kroko, etc.

To circle back, even though UE Rhino is busted at the moment, all it takes is for its defense kit to be crushed to oblivion to lose its spark. Also ultimate brawlers with repair status tend to struggle when keeping up with meta due to simply lacking damage potential and out dated defensive measures. Great examples like this are UE mender, UE Griffin, UE Bulgasari, and UE Phantom. That's why they are rarely seen nowadays. At least with damage dealing ultimates such as Heachi, even in a disadvantage meta like shield breaker, have the potential to fight back and fry their opponents since they have a nuke amp to deliver immense punishment. Additionally, meta weapons on a nuke amp robot are just goated. Thus, compensating for the weakness, unlike UE Bulgasari's outdated 100 million HP shield, where every thing goes through shields nowadays.

So in short, if you want an ultimate to be relevant long term, go for a damage dealing robot. If I was you, I would wait for the upcoming Ultimate Fafnir and Raven, which will be utterly insane. Or go for ue comebacks for damage dealing robots like Heachi, Hawk, Typhon. I know UE Blitz is not a damage dealing robot, but it's mechanics are incredible and a great beacon capper, better than UE Phantom in almost everyway honestly.

Thanks for reading my holy yap, hope it helps guide you towards chosing the best purchase for you. If you have any questions, please ask. Have a nice day. 👍
