Most champions can fit into this sort of thing if you are lose.
You literally just called it "cc on q"
"Aoe E"
"Cc ult"
However....
Leona has no dash
Amumu needs to hit an enemy to go to them
Nauti is the only one that pulls the enemy in
Vi is the only one that dashes before hitting.
Leona W is an armor boost with delayed damage
Amumu W is a AoE DoT based on max health
Nautillus is a shield with bonus aoe damage on attack
Vi is a third hit damage/debuff
Leona E is more like the Q category, firing in a line with a dash
Amumu E is an AoE with cdr being attscked
Nautillus is an AoE cc
Vi has anither on-hit boost that hits in a cone.
Leona R is an AoE with reducing effects based on distance from centre
Amumu is a snare on everyone around him
Nautillus is a homing knockup
Vi is similar to Nauti but she goes to the target rather than just a seperate blast.
Suddenly none of the abilities look the same.
The ordering of the abilities typically go:
Basic spell on Q
Defence/Buff on W
Mobility or Cc on E
Unique ultimate.
We can put some crazy champions into similar categories
Leona/Camille/Volibear/Trundle/Yorick
All have auto attack boost on Q
Aoe with some bonuses
Gapcloser E
Ultimates that generate insane pressure.
Yet none of these champions play similarly to eschother (aside from Voli/Trundle)
