I’ve posted my suggestion on these forums several times, but I still think it is a viable way to go.
I think Ludia needs to make each Arena dinosaur level specific. What I mean by this is that each Arena can only be played if you have a team of dinosaurs that match the appropriate level bracket. There are currently ten Arenas so for arguments sake we make each Arena into a 3 level bracket.
Fallen Kingdom (1-3).
Mount Sibo (4-6).
SS Arcadia (7-9).
Nublar Jungle (10-12).
Sorna Marshes (19-21).
Jurassic Ruins (22-24).
Lockwood Estate (25-27)
With this implemented you cannot play up but you could play down but only if you can build a team of lower level dinosaurs. That way you can make the Arena specific incubators be more relevant. Players who want to be super competitive can still play that way as they progress through them, but they will be facing suitable challengers.
Now some posters on the Ludia forums argued that my suggestion is flawed because it doesn’t take into account how much better an Epic or Legendary dinosaur is over the Common and Rare ones. However, considering that when you create an Epic or Legendary they come in at a set level then it doesn’t really make much difference as they will be facing appropriate threats.
Ludia could also keep the trophy count for the scoreboard and to determine tournament ranking as it wouldn’t impact anything or matter what dinosaurs you had.
