Good call....Certain types of spells have to scale differently. Damage and heal numbers are easier (and safer) to scale than percentage-based modifiers. After all, health pools of players and NPCs alike can keep increasing as we move up in levels, but percentage-based effects face that mathematical wall of 100%. That's why certain spell lines don't get upgrades from 61 to 70; there's no reasonable place for them to go and still retain balance.
As for the original question about whether Master II spells have too much impact on the next tier, remember that the Master II training choices are intended to be extra powerful and have a longer life than typical spell upgrades. It's not a bad thing if, in a lot of cases, the older Master II is on par with or better than commonly available grades of the next spell in the line. As long as the highest grades of the new spell represent an improvement, that is reasonable progression.
The level of the spell itself does not affect its chances of being resisted. That is determined by the caster's level and skill, as well as the resistability factor listed in the examine info (which is in turn determined by its quality tier).
In other words, if a level 40 Master II provides more benefit and less resistability than a level 54 Adept I, by all means use the level 40 spell.
