Re: Tether Manacost Increament & Overload distribu
T-Down both. Look at Io's pathetic stat gain. 1.7 INT gain isn't going to support much spamming, and as you said, it is Io's key skill and requires a lot of spamming.
On the other hand, 60 IAS for 1% HP+MP/sec is OBVIOUSLY going to be abused, and nobody would level it till extreme lategame. Perhaps 1.8/2/2.4/2.6 but 1% is too little. It's not even like he has a lot of HP to support it.
