^Yes. Let me explain :3.
These perks themselves would not change the game too much. Alone, they do not change gameplay very substantially. However, when skills that slowly pick away at the opponent (Spikey/Poison) and heal (Cure/Leech), these skills give a very large advantage to surges who run circles around patches and rams. On the other hand, Upper III + Berserker II + Full TA patch would be ridiculously unfair, especially in BvB.
