Eh, what does? As noted earlier, the X-Mansion gets wrecked and assaulted on a regular basis anyway.
I just kind of stop at, y'know, the most prominent symbol of mutant represssion- oh, and thanks to Cassandra Nova and Genosha- mutant genocide, being assigned the task of guarding the last remaining mutants.
Seriously. That's one thing I wish Frost had called Tony on- his company helping to design the next generation of Sentinels. (And yes, the ONE Sentinels are manned, which should cut down on various issues, but the symbology still remains).
