If you are dead when the Bardle Royale mode starts, you should not get a free respawn. You're warned 30 seconds before the event, if the Bardle Royale event hasn't happened yet, you should be forced to respect death timers.
The Guardian Angel reward. It's entirely too overbearing of a reward, any competent team can pretty much turn this reward into a free inhibitor or win.
Snowball fight, it's boring, favors waveclear comps too hard and the Summoner Spell cooldown reset when it ends is silly.
