I was planing on posting a tesla guide here lol since i saw a lot of them dying these days
The lazer one is fine , first things first tesla takes hell loads of damage becase of her limited range so patience and a good healer on your team is the key , your main role should be taking out bots that are running away with low hp
"ehhh but i want to go on harassing lnd bots like the other air bots"
Yeah do it with the shitty lazer range and you are dead!
Once you got sniper sight you can snipe people that are distracted too
Get the broad radar cart and the sniper sight so you can reduce your chance of taking damage by running into random enemys , izuna wisps are a great thing to put on her so get yourself one izuna leg for her =), take of one of her arms and put one with a shield or a long range weapon if you got the sniper sight and dont have much patience to keep on hiding untill you find a low hp enemy, learn how to play with your radar open a good position on the battle can save the day(and your ***)
thats the way i use her =) try to get at least 4 kills with her every time she respawns
sory for the bad english and im to lazy to write anymore , send me a pm if you have any questions
