The only acceptable weaponswap i would consider is if they made us choose a kit as our class mechanic as the weaponswap, and shoved the utility belt skills into our utility slots.
Other than that, no. Weaponswap as a concept is already awful to begin with, and half of the problems this game has could be attributed to it ( i'll argue the other half is the terrible boon/condition system ). I play engineer both for the aesthetics and also to get away from that terrible system.
