Reason to "collect" 5*s?
Is there a reasonable mechanic for which I should be concerned with trying to collect each of the 5*s that exist in the game?
Some background- I have a full 2* farm rolling, am very near to having the entire 3* tier championed (have all recruited and all but 8 championed) and have been steadily inching my way into 4* land. I currently have 38 of the 65 existing (including Valkyrie) 4*s, but most are at 1 or 2 covers and are by my estimation functionally unusable except as a "key" to open the "lock" of a required node.
While obviously I will eventually want to have the entire 4* and 5* tiers rostered, is the only reason to particularly care about rostering all 5*s similar, for unlocking the high end nodes in story mode? From what I have read, the high end PvP meta is all about the same 2 or 3 5*s (plus whatever the required character is), and the difficulty/expense of getting 5* covers through Classic Legends puts that well beyond my reach for the foreseeable future.
To put a point on it, I'm considering using some of my ~52 saved up Latest Legends tokens, both to increase my 4* roster and possibly to ensure that I have one of each of the current LL 5*s rostered for eventual use in Story mode required nodes. Is this a crazy idea? I already have 5* Ghost Rider rostered (random pull from an event vault) and a couple of Classic Legends 5*s (Back in Black Spidey and Hawkeye), so I'd be hoping to get one cover each of Archangel and Thor. I'm wanting Thor in particular, as the oldest 5* in LL tokens, and thus the most likely to be relegated to Classic status when Jessica Jones makes her debut.
