can only see 5 above and 5 below you. then again i think they did this so you just cant coast on events. I mean if i knew i had a 15000 pt lead over the 50th person i would not have to play that much 
I would imagine this will carry a large overhead. Displaying the whole collection as opposed to just a section could/would need a lot more processing power
They addressed this in the January Q&A video, at https://www.youtube.com/watch?v=v6FSezFt5as . Basically, the game’s underlying architecture means it would be very data- and server-intensive to constantly retrieve current scores. I’m sure there are ways to code a score tracking system that wouldn’t be so intensive, but those aren’t the ways the game was coded and it’s a bit late to change that now.
(Also in that video, they say that they can’t reorder characters’ skills to match their power strengths because of the game architecture - an RYG character has covers stored as Skill1, Skill2 and Skill3, rather than RedSkill, YellowSkill and GreenSkill; making that character YRG would change all your yellow covers to red cover, and vice versa. The worst enemy of ongoing development is hacky code.)
Would it be possible to see just the prize tier 10. Eg top 10 than 45-55 than 95-105 where a different prize would be awarded?
