Haste not working with bows

[trueido]

since bow can not be hasten and haste is huge damage bonus (50% haste = attacking 100% faster if you didn't know that) and most people already have above 50% haste with abilitys!)
maby just add a different statistic to all new bows?
like faster charge rate on bows like Marianos bow

or just 20% faster basic attack flat stat? since everybody attacks 50% faster already except rogues when they use bows, so flat 20% faster would make sense
