Sure, but rifles need to fight on their own pretty much the whole game, while volks have all kinds of support. (fastest AT, fastest rocket arty, stock heavy tank, decent mg, free nades/snare)
Convienently leaving out how Volks have no defensive structures, have to pay the most of all factions to get healing, need to buy their STG upgrade package always to stand a chance against anything other than stock cons, don't have any decent AI (anti-blob rather) vehicles and that this 'stock heavy tank' costs 1620MP and 515F to deploy (let alone that its performance is garbage).
Rifles meanwhile get free squads to back them up, have the fastest mortar, have mobile reinforcement & (fast) healing, free rifle grenades in fighting positions, the best AI heavy tank in the game, elite infantry with highest DPS in the game, best TD in the game, and the list goes on.
If you're gonna make these comparisons, at least be fair about it. Both sides have pros and cons.
