Trinket wards are OP... When actually UPGRADED and USED.
I get tired of having to actually ask/tell my teammates to upgrade their trinkets. It's kind of ridiculous. Hell, I even entered a Team Builder and before the game began I said "just a reminder, make sure you upgrade your trinket please"
The response I got: "Fuck off"
Really? Your response to me reminding you to buy the most broken, overpowered, game-winning item is "fuck off"?
Needless to say the players didn't upgrade it or even use it except for the scant few dragons we managed to take.
There was a thread posted a week or two ago that said: "If you're ahead you can afford to upgrade your trinket. If you're behind, you can't afford NOT to upgrade your trinket."
Granted I'm Bronze 1, yet I still see people all the way up into Platinum (I have to constantly remind my RL friend) who don't upgrade/use their trinket at all. It's 250 gold. That's... Less than 10 CS (with passive gold) to get what equates to a sightstone.
Do yourself a favor, play above your level, upgrade your trinket. And use it too.
