twisted treeline trinket displays stealthed champions!! renders stealth obsolete

If this is not a bug and it's a strategic piece of game play that is very broken. So I like the new twisted treeline I think it's a great update, however the new trinket that is great for looking in bushes also reveals stealthed champions. This renders champions like Rengar or Akali as well as many others, pretty much useless. Every 100 some seconds the enemy can use the trinket. Team fights happen about every minute or so, when ult's are back up, your opponents have 1-2 trinkets ready to find you... and kill you.

suggestions: 1- Remove reveal of stealted champions. or 2- leave in and increase cool down time, and make it have a smaller AOE effect. However this is still very broken item, as some champions can't move. or can't move fast enough to avoid being seen. still broken...IMO or 3- You could provide a counter trinket that super stealths a champion, but really..

option 1 is best Riot. please and thank you.
