The problem was/is that Me163s are such an easy answer to the guys who just spent two hours getting into position that even if you fail the first you can still intercept again, and maybe even a third time. They trivialize defense which makes defenders lazy. You can see this to be the case by how any approach near the HQ results in Me163s showing up. There was no consideration of whether or not to risk the perks, the Me163s were automatically taken.
