Haste rune shard overlooked?

Do you think the ability haste shard is overlooked? It gives 1.5 second reduction to w, and makes w and e share the same cooldown timer at level 3. You also get a 0.6 second reduction on q. I have tried it and I didn't feel particularly weaker or regret taking it over ad or attack speed.

What do you think? Does it have more value now that items have reduced ability haste?
