Gonna put in my cup of tea for this one. Yes, self breaching is long, and yes, some SCPs are pretty weak. Unfortunately, there are so many SCPs, where it gets to the point of a domino effect. When 8+ SCPs are breached, it becomes a huge mess, and just overall chaos for hours on end. If you made self-breaching faster, and SCPs stronger, it'd just make that domino effect even worse. SCPs like 096 and 049 might need some buffs, such as 096 needing to be damaged down to a certain HP to be bagged, or 049 requiring 3 or 4 armed personnel with weapons, instead of 2.
