[GAMEPLAY] Bug with Aatrox passive showing inaccurate amount of additional base AD
Aatrox's passive is currently bugged when displaying the amount of base AD he will receive when proccing his passive. Without any alterations to his base AD, his passive will display the proper amount (25% of his base AD). However, when he has any bonuses to base AD (aside from leveling up), his passive will display the wrong amount of base AD he gets from his passive. This also applies to the base AD he gets from his passive.
- Get something that increases base AD.
- Get 5 stacks of your passive (activating it).
- Look at the tooltip relative to the amount of base AD you actually get.
This bug is reproducible 100% of the time.
This is what his passive tooltip displays when there are no bonuses to his base AD (no faults)
As you can see above, when his passive is active, it will say that you get 22 additional base AD even though you only get 18.
This example isn't that problematic considering your passive is already active, however it gets very confusing when you get base AD from any other source, like 
Sterak's Gage.
This time, I've bought a Sterak's. Notice how his passive tooltip says that once activated, he will get 26 additional base AD.
However, once his passive is actually activated, he only receives 18 base AD. Since he gets base AD from his passive as well the tooltip only becomes more inaccurate this time around.
Aatrox's passive shows that you should get an additional 25% base AD once it is procced. However, this only seems to apply to your base, base AD, I.E the AD you have naturally from level 1 and the base AD you get from leveling up.
Thank you for reading, and as a final note: this might not be a bug with the tooltip, but instead a bug with how much base AD Aatrox actually gets from his passive. If this is the case, then fixing this bug will make Sterak's Gage a more viable option on Aatrox.
