Melee weapons question

Genuinely where is the fun in using a 2 shot melee weapon , it has nothing to do with skill so where does anyone get off on using them? Going invisible with a sword and one shoting them has zero business being in the game , stuff like this is why this game will forget get stuck in a C tier category until people just forget about it and the servers go off , bs play styles like this should never be rewarded with a 1 or 2 shot weapon it’s just all around ridiculous to me
