I suppose that could be. Historically, I have a pretty keen sense for keeping all the players roughly equally engaged. Recently, with these higher level spells, it does seem like I'm having to... worker harder, I guess... to get roughly equal engagement from non-spellcaster players when the spellcaster players are taking more time than they were before.
This came up recently in another thread. If you are having casters get unfair amounts of spotlight in the various pillars of play, run more encounters.
Because often the issue is that fewer encounters are run, leaving more slot to spend outside combat. Every spell spent in one pillar of play is one not available for other pillars of play by nature of the casting system (excluding Warlocks). While running fewer, harder encounters may balance out risk and attrition needs, it does not maintain the balance between the various resource recovery models. Frankly, fewer encounters favors logn-rest recovery over at-will.
So if you are running say 3-4 encounters per day, that's a ton of extra slots that can be used to replace cantrips in combat (upping their combat effectiveness) and/or to use for utility in other pillars of play (upping their effectiveness there).
This wouldn't be as visible in the lower tiers of combat where there are less total spell slots, but it's perhaps at it's most important now that you've hit Tier 3.
