As Td player myself and got crew skills all lvl 6 with average acuracy of over 85%.
1) there is a difference between sniping and camping and that difference from the majority of average players (45%wr) just don't understand.
2) meds and lt jobs are to spot and flank, td s are support tanks. Now some td can go aggressive i agree but not all. However I still believe as a td. Find a primary spot to support best your team and wait till all reds are spotted. (Of course some can be afk or very well hidden, so keep that in mind) then move to a secondary support position for your team. However be careful not to over extend. Sneaky lt can hurt your back, and most of the time if you call for help not many will help you...unfortunately. ..
3) always be aware of your flanks and who is not spotted (as red team) . Better run behind your ht mt cover and find a safe position for dealing massive amount of damage as possible.
4) if you're confident in your skills. Just don't care what yolo punks are saying.
