How to tweak Mord
Morde's a good champ, he just has a bunch of annoying bugs and could use a Tiny Polish.
So
Fix bugs
Passive: stays the same
Q: Same damage, but each successful Q landed on enemy champions grants +5% MS for 2 seconds(total of +15% Movespeed if all 3 Q's land)
W: Scrap exp passive, bring back overlap damage but only with allied champ cast. Lower MS steriod from 75 to 50, but without any decay effect, so as long as w is up, Morde gets a solid +50 MS until deactivated. Also, allow solo cast(no minions or allies around) to do DoT, but half the damage than the non overlap DoT you would get from a minion cast. Also, the full solo cast has a larger AoE since it is much much weaker. OR on solo cast have the normal size AoE but the damage is based of %missing hp.
E: stays the same.
R:stays the same.
This gives Morde a better feel of a JUGGERNAUT. It also keeps him with 325 base MS and poor base stats, but damage and WINDOWS OF POWER TO STICK OR RUN AWAY.
It's thematically fitting for a juggernaut, and buffs Mordes Movespeed without buffing his base MS or other stats.
