Titanic Hydra is only 78%cost effective w/o passive
did you know titanic is 78% cost effective now? while ravenous is 96% I agree with making titanic hydra less cost effective than ravenous. that's a no brainer since its less risky. However making it nearly 20% less cost effective might of been too much.
Prior to the nerf it was the suggested build for Aatrox on champion.gg now its hardly listed as core build on any champion.
Suggestion give it +5 ad +100% base health regen out of combat.
i think this could be a great item on him Aatrox. Since he can get his health back while jungling, clearing camps faster using blood price more often.

Devourer being removed means titanic won't be as op as it used to be in the jungle.
this way its closer to 10% less cost effective which I think is more fair. replacing some of its raw stats into utility keeps it from being too strong in battle but handy over extended durations.
With ravenous you can replenish your hp a lot out of combat, this would help stand up to that.
ult proc.
mean while titanic hydra's passive provides wave clear and HP scaling dmg. Those are actual numbers and stats that are gained and can be translated into calculable values.
