This is my philosophy with things. If something can be bought with real money in a single player game I've already paid for, I have no problems using mods or cheats to get the same things.
And I'd say they are even worse in multiplayer games. MTX that affect how the game is played is just paying someone to make it easier for you to win, which is pathetic whether it's a single player or multiplayer game.
I would probably recommend not using these mods, or at least limiting their usage. The MTX subverted the design intent of the game. These could potentially make the game worse.
(I haven't played the game and can't tell you if the game was designed worse for MTX, but everything I've seen and read indicates that it wasn't and those were forced in as an afterthought.)
