Recently, I don't know when exactly, there has been changes in the first part of the tutorial making it literally IMPOSSIBLE to beat the WR. These changes are about Darius' skills. in the WR, we can see that all of darius' skills are max level. now, they're not at max level. his R is now lvl 2, making the reset only work for 20 seconds. making it impossible to do the WR strat (ult yasuo to get the bonus damage, break tower, ult sion when he's here to get bonus damage on inhib, then ult everyone else for the bonus damage on nexus turrets and nexus) because R runs out of reset time, so we can't ult sion, and ult goes on cooldown.

That was made a long time ago. They've fixed leveling up abilities while cutscene, you could max them before by holding Ctrl and mashing QWER. Just wait for tables clean up for new season/pre-season.

You can still do the levelup glitch. You just do it while switching from MF to Darius instead.
