I actually dislike how they are potentially removing all of these invocations. I've played a lot of warlocks since the launch of 5e and frankly Eldritch Sight and Eyes of the Rune Keeper are two of my favorite invocations, to the point where I almost always have at least one of them. I'd argue strongly neither is actually a "trap option" and it's led to quite a few moments in several campaigns where my characters have been able to gleam information off of old cave walls, "dead" hieroglyphic languages, or other various similar things in game. I suppose one could argue that maybe this could be considered a "problematic" invocation in that it can catch unprepared or newer DMs off guard, but that's a whole other debate.
What irks me about the removal of all of these low level at will invocations is that they locked ritual casting behind Pact of the Tome, it basically makes (for me at least) Pact of the Tome essentially now a required invocation for every warlock. I think this is just bad design. Frankly I think if these invocations are getting the axe the base class needs ritual casting (I also think the sorcerer needs ritual casting too, but again, that's a tangent for this thread). You also can't even make the argument that they just need to trim redundant invocations because they let stuff like Mask of Many Faces and Master of Myriad Forms still both being present. Do I like that they did the sensible thing and reduced the warlock levels for many invocations? Yes. That's great. Do I think it's comical that Not 4 levels after taking Mask of Many Faces I can now take another invocation that makes my first selection utterly obsolete? Also yes. Especially when they removed the ability to swap out invocations on level ups.
