Yes. And you can run out of range 2 from the wizard tower. Then it is totally useless for attacking the enemy mage.
Good players will not be beaten by just using wizard tower, jinx and a random attack spell. This strategy exists since wizard tower was released and has seen many many counters. You just have to be prepared.
I think we need to play.
Time to chime in I suppose and bring this ship back on course.
Sidenote:
The ability to lose means nothing in a game of random dice. I have seen Bloodwave warlord decimate Wizards from amazing rolls alone. Does not mean that BWW is OP or better than Wizard? No.
Great players lose from Wizards Tower all the time, to say otherwise would be to suggest that it only bad players will lose to Wizards tower, which is not true. Wizards tower can win games and other times it can be more trouble than it is worth; being destroyed in one quick action from a lucky roll. It is one card and Mage Wars is won over the course of multiple rounds. Wizard Tower is just a really really strong card, in an already potent school, that plays to the major strengths of the wizard's wheelhouse.
All that to say:
The complexity of this "issue" is two fold.
The wizard and the arcane school.
The wizard possesses a statistic advantage in mage wars. Not only does he receive zero spellbook restrictions, The wizards abilities are top tier; voltaric shield and arcane zap are both > tough, melee, curseweaving, treebond, deflect, veteran tokens, battle orders, wounded prey, archery, fast, plague master, or divine reward. That is why more often than not a wizard imitation can do what every other mage can do but better. At the end of the day there is only one way to win, excluding battlegrounds, destroy the other mage.
Then there is the arcane school. It's like a coworker who you don't really like, but gets his job done like no other. There are mechanics rooted in arcane that not only one card shutdown books, but do it without defense. Arcane has the best spawn point and arguably two of the top three familiars. It commands the tit for tat counter game and can not only out pace other schools, but also play attrition while it is doing it. No other school can switch gears or even has as many tools in their respective boxes. Unless there is a massive change in the way that mage wars is played this is unlikely to change in the near future.
Long story longer:
The reason that anti-conjuration is being chanted in the deep is that the wizard is dependent on conjurations for the majority of his mana boost / denial, and action efficiency. However you cannot give everyone a "destroy conjuration" spell. While that would indeed change mage wars, it would have some serious ramifications across most of the mages, some more than others.
