It's all good.
Yup.
I have this discussions like this from time to time with my players and with people here on the boards. For example, do you take out many smaller enemies first, or do you take out one more powerful enemy first?
My philosophy tends to be to take out many smaller enemies unless they do not seem to be effective. Fewer enemies typically mean fewer counterattacks.
In the case of Mirror Image, you have two choices:
1) You can ignore it which means that your are ignoring an arcane spell caster and the images are providing even MORE protection for him, giving him the flexibility to decide on a wider variety of actions. OR
2) You can focus on it which means that the arcane spell caster might be in serious trouble and the images in fact provide LESS protection, forcing him to worry about attackers as opposed to him being totally free to pick and choose targets at will.
I choose the latter. Make the spell a liability instead of an advantage. IMO.
The fact is that in a high level campaign, there are many ways to take out the spell in a single round.
A Hasted Wizard opponent can easily take out all of images with two magic missiles spells.
Two enemy bowmen can take out the images.
A single Targeted Dispel Magic or Greater Dispel Magic will often take out the images (and possibly other magic on the caster).
An opponent spell caster with Minor Globe or Globe of Invulnerability can walk up to the caster and temporarily take out the images.
A single Chain Lightning spell or Mass Suggestion spell will take out the images.
But, the downside to the arcane spell caster using my philosophy is that opponents are targeting him as opposed to someone else, BECAUSE he has Mirror Image up. Yes, it protects him for a while, but it also makes him a target. And, nothing says that an opponent will not get lucky and actually hit the arcane spell caster multiple times.
The best protection in the game is to not be a target at all. Mirror Image gives the illusion of that, but not if the opponents are played intelligently. Instead, Mirror Image can do the exact opposite of its intent. Again, IMO.
