Advice on hangar

I’m the type to only use one hangar - I can’t handle upgrading copious amounts of robots and weapons. That said, can yall tell me what bots and weapons to switch out with the next update coming? I have a bunch of decent bots but they’re underleveled as of now.

Also is my Indra cooked? ;-; I have vajras on it and both the weapons and the titan are getting nerfed. I don’t know how hard the nerf will be should I like switch Indra out? (I have zmej mer, scavenger heimdall and aether but all low level)
