After playing and trying premium tanks extensively, I've found my personal worst performance tank I have is the STRV S1 by far, Imo the least competetive premium tank in the game at teir 8. Despite its extraordinary gun which can take on teir 10s, it depends widely on RNG to not flinch the accuracy which makes up the one and truthfully only true "dependable" features of this tank , its gun. Because of the tank's extremely low HP, armor, and traverse it isn't rare to get 2 shot, even 1 shot in cases of teir 9 & 10 battles which is the vast portion of the types of battles the STRV S1 is put into.
The tank is highly situational, and if you don't have the perfect position to not get spotted (which mostly fades after taking your first shot), or the perfect accuracy rolls, you're pretty much dead meat if the enemy gets anywhere near you because you don't have the traverse speed, and definitely not the accuracy considering you can't shoot when you're not in firing mode. This is especially true in Urban maps such as Himmelsdorf where the enemy can flank you from many different positions and you can't turn around to face them without them shaving off 60%+ of your HP first.
This brings to my conclusion, does the STRV S1 need to be buffed? Yes or no, state your opinions but ONLY if you actually own this vehicle please and have experienced the tank first hand, as my opinion is formed based on experiences I have had with this vehicle daily. If it should be buffed, even slightly, what could be changed about it to make it more competetive in the community? If not, why?
