Upgrading teslas- Trapseption

[TR3V0R]

I've been using Trapseption and its cool. For those of you who dont know, this base uses teslas to lure in giants to spring traps. The teslas aren't protected by walls and are destroyed easily. Do u guys think that upgrading the teslas are worth it (as they are just used as bait) or they'll just be destroyed again? Mine are just lvl 3-4.
Thanks

Yeah teslas are definitely worth the upgrade

Im using this base now and my tesla are upgrading. I had the same thought. Then I realized it was definitely important for 2 reasons:

1. Giants will go for upgrading tesla anyway and...
2. If I ever wanna change my base I'd better do the upgrades.
