I was on Excel earlier today, a Tuesday morning JUST after maintenance, and LFG was hopping with several teams, TFs, and people looking for teams.
But I guess you weren't asking a question just stating a flawed premise, so, ...ok?
Would it be possible to get some sort of marker on player names in the team/league window who are 50? When forming a league that would make it super easy making sure all teams are good. My idea would be a slight gold outline around their name, or maybe some sort of symbol next to their name, whatever is easiest to implement.
Just want to add that I love having tons of NPC heroes and villains running around like the characters you mention, both in the world and in missions. They can be lore heavy famous characters, or just some two-bit character, doesn't matter to me. It makes the world feel much more alive.
I mean, now you got me thinking....
Tier 9 Blast - Shinobi Ichizoku
"Summon your Shinobi Ichizoku (ninja family) for a brutal, area attack around your target."
I'm picturing smoke, ninjas darting around, then disappearing quickly. Knockdown so when the ninjas leave and smoke clears the baddies are either dead or trying to get back up.
