As long as it stays that way and the game economy is reasonable then I'm ok with it.
If they add the option to buy them with real money then no bueno.
Assassin's Creed games had MT since AC3 and every single year there was thread where people complained about it and every single year we got AC game where by the second half of the game you get so many resources that you can buy whatever you want from merchants. I don't like MT and i hate loot boxes but i never ever felt that MT impacted any of the Assassin's creed games. Hell many people didn't even noticed that they are in there.
