Are proliferating perks a danger to GURPS?

[mlangsdorf]

SWT buys off an arbitrary restriction on large shields. Large shields were already unpopular because they weighed 25 lbs, which meant your character was slower. And the difference in combat ability between a Move 6 character in light armor with a small shield and a Move 4 character in medium armor and a large shield was already generally weighed in favor of the small shield.

All SWT is make large shield characters slightly more viable. It doesn't break the game. If there wasn't a completely arbitrary penalty on attacks with large shields, it wouldn't even be necessary.
