I sup main and I'm yet to receive more than two honours per game under the new system. Even if my playing is instrumental to the victory, and even if I'm the only one with an S, the honours always just goes to the person with the most kills or whoever got that penta. As a support of course I'm actively trying to avoid getting kills and doing showy plays myself, but rather enabling my team to do the same.
Yet another reason nobody wants to play support. Mind you there's a bright side - at least that means I almost always get my preferred lane.
