Sherman is medium tank, of course it's better than luchs. Ostwind is a T3 AA vehicle that is more deadly than ISU and Brummbar against infantry and could shoot down planes for a cost cheaper than P4. No denial that Centaur is also better than Cromwell for example, but not to this level and it takes quite a lot longer to get one because brits need mandatory sidegrades for their infantry to fight.
lol, it has same AI as centaur
brits and osther pays the same to reach tanks with or without weapons and nades
115+30 =145 briys
90+40+15= 145 osther
if we add upgrade and tier
115+30+15+10=170 brits
90+40+15+10+20=175 osther
and no, u don't need bolster, IS beat green at all ranges already
i even posted the video of their AI, u are delusional
