In some cases, it will mean an easier match, in some cases a more difficult match, however this is a very selfish way excuse to put in no effort. No one would accept that in PvE, if someone didn't like a specific dungeon, a player just sat on their virtual butt and announced "carry me, I don't like this dungeon, but I want the rewards". They'd be kicked. it's not mandatory content, if someone doesn't like it, they're expected to put in the effort.
