Greetings!
I wanted to give my feedback on a rather underused, but interesting skill - mana shield. The thing is, in lod, maany people pick oracle/zeus/storm/qop/other int carry heroes. But they always go for boring agi/str carry setups - essence, swipes, marksmanship, that sort of boring thing. Rarely glaives/arcane orb gets taken. The problem is, there is hardly anything to differentiate int carries from str/agi ones, and the lower bat benefits typical carry builds as much.
The reason is, if you go for int items, you get overkill amounts of mana, and there are few ways to spend it. Arcane orb is one good example, rolling-on-floor-lightning is another. That is about it. Mana shield should theoretically work, but, there are a few downsides. First of all, the alternatives are as strong if not stronger - blur does the same vs attacks, and also does not require obscene amounts of mana, does not prevent you from casting in extreme cases and so on. Backtrack/dispersion do not give as much ehp, but are not weak vs illusions and so on.
I would reccomend giving mana shield some more strenghts - either 60% damage reduction, or some interesting gimmick, like, say, x% of total mana regenerated per second, or something. Would be a great boost for int carries/tanks that actually feel different than their agi/str counterparts.
Also, I feel lame being the only one to pick it
