To start I really love to use fully charged heavy attacks both to regen resources and to do damage when is a good time, I also love the sets that will proc some buffs using light and heavy attacks but, as everyone, I know that fully charge an heavy attack is a loss in time and opportunity (mainly a loss of dps in pve and a telegraphed action in pvp easy to counter and counterattack), in addition they are pretty pointless because of their damage compared to other attack skills (an example is Crystal shard and its morphs and solar flare and dark flare, or wreking blow and snipe, every skills listed before deal a lot more damage and have a faster casting).
I was thinking why not add a new statistic like Haste with a cap (maybe a 40% cap) used to increse ONLY the casting (or channeling for lightining and healing staves) of heavy attacks (mainly because casting skills with a cast time is already usefull and fast and applying this addition to them too would be for sure a balance changer)?
Plenty of other games have something like this (I mean the statistic) and work very very good, we already have very good sets that buff heavy and light attacks and I think with "Haste" would be very very cool to see people create builds and theorycraft around new builds other then spamming the same skills, using the same set over and over again, in addition we would see people (mainly in pve) using "a rotation" of heavy attacks to regenerate resources and take advantage from set's buffs so we could see some other classes used as healer in dungeons instead of the classic templar spamming Breath of Life and spear to make melee regenerate stamina.
Lastly DKs too will benefit from this addition to the game thanks to their skill Molten Weapons (and its morphs) using all kind of weapons not only bow and this, well at least is what i think, would be a little but very important fix to the Whole class without touching anything in the core skill system.
I really would love to see my DK casting fireballs and frostballs from my destro staves in pvp without being completly useless and harmless.
PS: i know probably adding a new statistic is not so easy like I said, but as I said everything would benefit from this addition without touching or change anything at all in the game (classes, races, items, skills, passives, etc.), afterall what we have besides weapon crit (spell crit) and weapon damage (spell damage) and armor (spell resistance) to be used in combat? As a dps we will use crit and damage and max them as well as we can, as a tank we max health and armor or resistance, as healer look at dps; with haste we will have something new to work on to make the perfect build that suit us.
While I hope ZeniMax see this post, what do you think guys about this addition?
