Geo tighten

A lot more info would be helpful...

They have a TM train that they can run if you don't counter that. Even doing less damage per hit, they can still win if they get enough attacks. 

More than anything we would have to know what teams you used against them to be able to explain this to you. 

But I'd be willing to bet that you're not using Traya lead. 

We'll help if you can provide the relevant info, but I think just how you phrased this tells us a lot. It seems you think that only the relic delta is relevant, and that if you have higher relics, any toons will win. But that's not how it works. Some teams are counters against some others, and will outperform their relic level. You'll have to consider more than relic delta if you want to win. 

Do you happen to be in Territory Wars? You know, the one where Poggle's Omi is activated?

"At the start of battle and the first time an ally is summoned, Geonosian allies gain Geonosian Brood until the end of battle or they are defeated, which can't be copied, dispelled, or prevented.

Geonosian Brood: +20% Max Health, Max Protection, Offense, Tenacity, and 10 Speed for each Geonosian ally; when this character is defeated, revive at 100% Health, Protection, and Turn Meter (excluding summons)"

Making them massively more chunky? Also, what were their mods like? What were yours? What kind of datacrons, if any, were at play?
