Haste doesn't benefit Traps?

As Haste aura, I find it strange that it only improves Casting and Attack speed?

It should improve Action speed so Traps can benefit as well.

Thoughts?

We don't "cast" traps anymore, we throw them.

I know. That's why I think they should change Haste to action speed buff.

Or simply add "Increase Throwing Speed"!!! Simple fix.

Cast speed and Throw Trap speed are two separate things. It's at the very base of Slavedriver/Architect's Hand, which is an item you could use if you really wish to recycle Cast Speed from Haste for your Throw Trap Speed.
...And your Seismic Trap wave release speed. Nice idea, perhaps I should hit more often the Temple.

Nevertheless, as a general tip changing it to Action Speed would make sense, but need to be implemented correctly. Haste gives more bonus to Attack Speed than Cast Speed, and more to Cast Speed than to Movement Speed. So, it should boost Action Speed only for a little part, and still have AtkSpd and CastSpd bonus, albeit at a lower magnitude than now. The end result is that Trapper/Miners would get a very little bonus for their Throw/Placement speed

I actually like the idea. Haste is a bit of an underused aura and this would give it a reasonable boost.

I don't like paying 50% mana for Haste that doesn't really increase that much. Throwing Speed is something that is not as common as Attack and Casting speed. If Haste gives good Throwing Speed, I may use it if I need to kite more.

haste should speed up everything and not just attack/cast. I think Action Speed is what Haste should offer. We already have many ways to get Attack/Cast speed.
