I’ve been experimenting with them lately and there’s a few variations with the droids...
Super TM lock teams... like HK (L), 88, T3, IPD & BB8... or 88 (L), L3, T3, IPD & BB8... both are very strong in the right circumstances.
Or variations using CPO & R2 which utilize cpo’s kit...
You can even run a leaderless droid team with some success... like 3PO, R2, BB8, T3 & L3
T3 Is crucial for making them viable... and should always be on any droid team...
BB8 being on the team also makes them move super fast and have a chance to shut down the opponent before they can move...
Their success is very dependent on gear and even more importantly.... zetas!!!
They need a lot of zetas to really shine...
But they are super fun to play around with and can be very strong if you are willing to devote the resources to them (even vs the current meta teams)
They are potentially super strong in TW & GA... most people don’t know how to fight them or just can’t keep up with the speed if BB8 is on the team... I’ve had more than one opponent completely flounder vs my droids in GA...
So yeah...
Droids Rock ;)
