some suggestions to shop. also a bug/? on Malph

There is no suggestion board here like there is on other servers... and I don't even know if my post is read on the other server I am on, so I am posting here too.

1. When purchasing armor/MR, it should show you the % increase you will gain. Is it worth getting 150 armor or stay at 120 and go for 300 more hp...hmm...
2. It would be cool if you could choose an enemy champ while in the shop and it would calculate the armor/items they have, so you can know how much damage your/their spells/damage do to you/them.

And my question: his W says he gets bonus physical damage which splashes to enemies around his target, but he doesn't do increased damage to towers with it, nor does his splash effect towers. it should be reworded or allow it to effect towers.
