Premise:
We can all agree that the fixer team meep is both a valid part of the fixer's toolset yet, at the same time, overpowered in it's use regarding notum wars tower battles. It would be dishonest to both sides of the situation to either remove the ability or leave it as stands. Having anti-meep towers or anything of the like is more complicated than it needs to be and will just result in different tactics to negate the changes.
My Proposed Solution:
It's simple. I propose a 10 second capped cast time for all team meep nanos. That's the only change. Self-only stays the same as is. The time period is short enough not to cause too much of a problem for it's intended use of transporting teams back into the grid from far away places. It will still be, by far, the fastest way to grid out. It is also a long enough time period to give tower defenders a chance to take out the fixer before he executes his nano or, at least, time to interrupt the cast. Or they can take out at least 1-2 members of the fixers team before they get away. But at the same time, it still gives the team a way out if they can survive long enough.
I think that this is the most balanced way to approach the situation. If anybody has any better suggestions, I would love to hear them.
On a side note, this topic is not here to discuss Omni vs. Clan. Both sides have and still use the tactic at tower wars. I advise the mods to remove ANY posts that try to sway the topic in that direction.
