Skarner - delaying the spire updates on the minimap could aid his situation

I'm sure one the main reasons skarner's passive gets so much hate, is because everyone can look at it from the minimap. A good fix to that would be, if not remove it entirely, delay the spire updates on the minimap, say e.g. to 10 seconds, or 20 seconds. i say so because these spires retain alot of skarner's powerbudget, they're skarner's thing, and they are already easy to contest. the fix i proposed would encourage more aggressive plays from skarner players, such as invading. Let me know what you think!
