Also, anymore than 1, is overkill (not to mention less and less efficient/useful due to diminishing returns). Later on, with dual weapons and flb advent weapons, you'll get tons of HP without trying anyways.
And yes, it's fine to fodder gatcha SR weapons. You'll eventually end up using all SSR weapons for the stats anyways.
