The intentional parallels between Nasus and Renekton:
Both have auto resets 
W 
Q
Both have AoE abilities Q E
Both have healing of some sort Q P
Both have ultimates which grant stats or resources over time as well as AoE magic DMG per second.
(Also max health)
I know, pointless post. I just wanted to point out how differently two similar kits can be played. It's interesting.
Shreddermen572 votesI mean, they are brothers after all.
So it does indeed make sense.
Titanium1251 votesYep! :D (Also see Rengar and Kha'Zix)
Jaspers1 votesBoth have armour shred too.
Not only that, consider that Renekton is a early game champ, usually dominating lane, like his character in battle. While Nasus takes his time, farms then dominates mi.. I mean late game.
Cowgirl Ed1 voteslate game nasus is garbage, you were saying right: mid game
Enderspider1 votesla.. i mean somewhere 250 mins in when he is disturbed while farming his 3522nd stack
Enderspider1 votesziggs and xerath are pretty similar too
auto attack modifier: 
passive
long range spammable poke ability: Q
ranged hard cc/peel ability: W E
poke ability with a slow: E W
both have semi-global ults
both have ridiculous waveclear
theres probably some more of these combos in the game(looks at janna/lulu)
Titanium1251 votesI was pointing out the lore differences, As ZIggs and Xerath have very different playstyles. (Ziggs has some mobility and can shred towers [Although everyone can do that these days]) Xerath meanwhile has really broken abilities if you land them. (Only if you land them.)
Enderspider1 voteswell they both like breaking stuff (ziggs likes breaking stuff in general while xerath likes breaking azir's hopes and dreams, as well as logic)
also they are both poke champs sorta
Titanium1251 votes:D Yeah they are both poke champions. Also feelsbadman Azir :(
