Having no addons would just make greater pyroblast harder to deal with anyways because players would be even sloppier, so if they’re using it in addon play then they’ll definitely use it in no addon play.
People don’t really fakecast either, they just eat the kicks most of the time. It’s even more likely to be effective on LAN because again, people are that much more likely to make mistake. Online tournament play is as close to the best play you’ll get and even then it was still useful.
You’re not really thinking very logically it seems.
Seriously, first you assumed it was being used because the games were on LAN and therefore no addons so it was easier to get then off, but it turns out that no - the games are online with addons on so fewer mistakes are made. Now you’re essentially going back on your own initial logic which was that offline play is sloppier hence they take greater pyro.
The tournament this weekend was literally the best scenario to possibly counterplay greater pyro. A rogue mage mirror. Bugged neurotoxin. Addons on. Still incredibly powerful and useful. You could not have had a more optimal time to NOT take it, but it still was. Nothing can counterplay Gpyro as hard as a mirror, and again with Neurotoxin bug they shut it down even harder and it’s still played lol.
