As most players would know by now, the meta shifted from raptor to tanks, eg. steogodeus and the likes. Now everyone is gunning for the tanks.
This will change with dot (damage over time) after the next update. Since damage is based on % of max hp, it doesn’t matter how massive your tank is, it’s going down fast.
I believe that Ludia is going to “rebalance” the game using next update so I think it would be prudent to not to dump excessive resources into tanks only to see them nerfed like the raptor squads
