Meditation/Expanded Mind Changes and Mid-Lane Mages

Here are the Utility mastery changes currently on the PBE:

**Expanded Mind Swapped places in Utility Tree with Meditation Changed from "+2/3.5/5% increased maximum Mana to "+25/50/75 Mana" **Meditation Swapped places in Utility Tree with Expanded Mind Changed from "+1 Mana Regen per 5 seconds (per rank)" to "Restore 0.5/1.0/1.5% of missing Mana every 5 seconds"

In particular, I would like to look at the effect of this change on champions who go with 21/0/9 masteries (or, more generally, champions who put enough points in Utility to use the new Expanded Mind but not the new Meditation). Such champions will be losing 1 mana regen/5 (per rank in the mastery) but gaining 25 total mana (per rank). So, the amount of additional mana provided by these masteries will be the same after 125 s (2:05 minutes) on the field. This feels to me like a nerf to the early laning of champions like Syndra, Ziggs, Xerath, Lux, Kassadin, etc. who need to stay out to farm for several (i.e., more than two) minutes at a time in the early part of the game. For my part, I play Syndra and know that I have to be very careful with my spell casts until I'm able to afford Athene's or something similar. Some won't have a problem with this (and I do think there are some positive things about these changes as well), but for my part I feel that these mages are already a little too strapped for mana in the early game, and I'm afraid these changes would exacerbate that.

Would be interested to hear any thoughts on this. Granted, it's a rather small difference I'm discussing, but sometimes the difference between winning or losing an encounter is having the mana to get that one last spellcast off.
