I saw some discussion of different types and numbers of minions we can expect. What I haven't seen is mention of scaling. I don't just mean level scaling of minions vs the player, CoH did that and I read in previous dev posts that CoT will basically be using a similar system.
CoH mastermind pets also scaled alright using loot just like any other power, although they needed a variety of stats compared to most powers since they had their own defensive stats which made things a little more complicated.
I never played CoH all the way up to raids and endgame stuff, I always kept making new characters, so perhaps this issue was addressed years ago.
My concern is that many games have late game methods of character power growth in addition to the standard stuff, and content is developed around having that power. But pets might not share in that power increase. If pets only scale from a player's level, for instance, and they gain benefits that don't increase their level, the pets get left behind, punishing commanders compared to other archetypes.
I don't know if CoT is going to use inspirations in a smilar manner to CoH, but a similar situation comes up with those as well. If they only affect the player they are inherently weaker for a commander compared to other classes. My memory is foggy here, I seem to recall there might have been a way to share inspirations with your minions in CoH. It has been a few years.
