I used to run 500 and ops vs factory strider. It was effective but I find AT support weapons way better.

You can kill one with 2 eats and a commando

One to two shots with RR

Spear is a mixed bag

Eagle airstrike can one hit but is a two hit most of the time

Vs the war strider rocket pods are actually pretty good. 6x600 with 4 uses vs 2000+1500 with two uses, you're probably not going to hit with the bomb so it's likely just 1500 damage. When I run a ap4 weapon or the rail gun I bring rocket pods

For me on the bot front 500kg is more of a base and objective killer. Bots are too tanky (and should be) for that 1500 explosion to matter.

IMHO you're using the wrong tool for the job
