Warding Trinket Tweaks
So there are a lot of issues with how warding has changed this season, but one I find particularly annoying is the lack of a pink trinket. I don't always have an item slot to spare for a pink ward amd having a pink ward out is more essential than ever for the vision war. My solution is to create temporary "modifiers" for the trinkets. If I want a pink ward late game I can buy a pink modifier for the same price as a pink ward. This was cause my next, and only my next, ward placed with the trinket to be a pink ward. Doing this saves an inventory slot, but uses one of your trinket wards, creating a pretty heavy opportunity cost.
This could also open the options to other trinkets modifiers of this nature. Add an extra charge to your yellow trinket, make your next blue trinket shot place a stealth ward (which is timed and counts towards the max like normal), next sweep lasts longer, next sweep has larger range, etc. Not all of these are great ideas, but the preseason would be the time to figure out what works and what doesn't.
