You read them. The only thing specifically changed in the tiger playlists was the additional blue and purple engram rewards at the end of every round in the reward screen. The individual enemy drop rates are the same as every other enemy. Reading comprehension at its finest...

[quote]No, in the Vanguard TIGER Playlist, the drops for legendaries and blues, including rewards, have been increased. Read the patch notes, bruh.[/quote] Read the patch notes again "bruh"... Rare or legendary engrams have been added to the reward list of the tiger strikes. Reward list is the end of the strike, after killing the boss. Nothing was changed on trash mobs. So before talking about patch notes you should read them "bruh".
