I like all the new features except for the pillagers. I hope an optional game mode is added that doesn’t have them at least for single player offline play. Or they only spawn under easily avoidable circumstances. Otherwise I will have to revert to 1.13 or just not leave peaceful mode ever.
Raids are easily avoidable, but as far as Pillagers in general, don't think you can avoid them unless you were to make a mod that makes them unable to spawn.
