Discussion about Titanic and Revenous Hydra

These objects are often a key part of the build of different Champs, but in my opinion one of the them is better than the other: the Titanic, for me, wins on Revenous and I'm going to explain why: Although the gold efficency is greater for Revenous hydra (96.43% without active and passive abilities) than Titanic Hydra (92.86% non-passive and active skills), the difference is just the passive ability, which allows Titanic to scale better with other objects getting offensive and defensive statistics at the same time. In my opinion this is one of the reasons for the birth of Tankfiora and TankYi. On The other side Revenous has good of damage statistics, but they are not enough to justify the purchase: 75 ad from Revenous against 50 + 5 + 1% max hp of Titanic. Imagining a regular champ bruiser that easily reaches 3000 hp, the Revenous would give him 75 ad flat (which scales on skills); Titanic ,instead ,would give 50 ad+ 5 + 30 (35 extra damage are calculated as bonus on hit). So Titanic is better then Revenous expeccially on champs based on aa (virtually everyone who also used Revenous) In the end I think Revenous should reward more who choose to go glass-cannon with more offensive statistics. What do you think?
