If you're thinking there's been a lot of record-breaking going on in ALGS this split, you're right. It's not coincidence, it comes back to one ability - Maggie's Riot Drill.
@ImMikeyyyz's record breaking 4.7k had more than HALF of his dmg come from the drill. The top 4 single game dmg records are now held by Maggie players from this year.
Here's a great example from
@PanicApexx of how quickly this can rack up in an end-game, 300 dmg from a single tactical use. No other ability comes close to this in dmg output.
Don't expect dmg records to come from anyone but Maggie players anytime soon!
