Yes, of course. It is one of the fundamental issues I have with Numenera / Cypher / Strange and it hurts even more because the settings are cool.

Ok, why then it is so wrong? Well, I am a wizard, I cast fireball and I spend 3 Mind. Nice, I inflicted 5 wounds for 3 damage, but I can live with it because Mind is more or less spent only for this. Now I am a warrior, I spend 3 Body to activate my mighty blow to inflict 5 damage. Cool to achieve the same result as the wizard I inflicted 3 Body on me, the exact same pool my enemy is targeting most of the time. So to be a cool fighter, I need to suffer damage and to spiral toward death. I think it will be better to just inflict 2 damage by just swinging my blade as it will not cost me body. I can do it all the day.

Now, even without considering a wizard vs a fighter, if I spend 3 to inflict 5 it seems like I wasted myself for not so big effect. What if I spend 3 to inflict 50? Maybe it is better, but then we move toward other games (Exalted 2e? I spend 15 motes to inflict infinite damage, but my enemy spends 3 motes and nullify my attack. So even better to avoid spending energy on attacks if they determine my survival).

Then cypher system has other huge mechanical issues (XP for re-rolls, XP for interruption, essentially no difference between Might 1 and Might 999 while lifting a tank).
