Trinkets now auto-upgrade at level 9
Since the community is pretty slow to realize the power of 
, I'd be down for it just upgrading automatically. 250g isn't a big deal, and if it is just balance around that. Besides, it feels bad having to choose between finishing an item or getting the upgrade.
Not trying to complain or flame the people that don't upgrade, I just want my team to have bottomless wards on hand without having to remind them. Sure, some people still won't use them (I saw a statistic somewhere that lots of bronze players don't even use their trinkets), but nowhere near as many as the people that just don't buy the upgrade for whatever reason.
