Yeah, that will be cool.
But I thinking the swing hammer can be potentially used on the zvz and small groups fight, when the e is casting the hammer will swing for a short time, after the casting end will jump in a distant and samsh the ground with huge damage in the spot where it land, like the boss in corrupted dungeons.
I think 1h hammer could have it's niche if they reduced it's CD even further in exchange for an even smaller stun area.
Trade off mobility and bigger stun aoe for more frequent ones. I think it being 1 handed isn't enough of a benefit for it's lack of reach or mobility.
1H could use a rework. BUT, it has a place in PvE, you can see it being used in Avalonian Dungeons, Group Dungeons and such. Forge Hammers people! FORGE HAMMERS, PRETTY PLS. The weapon is more dead than the two weapons that currently have “Life” on their name (ha, ironic )
Hmm, another dedicated tank weapon which focuses on inflicting CC at a range would be a nice addition, specifically one that could be used in small group play, HG's, CL's and the like.
Arcane staves, Tombhammer and Polehammer exist, of which only the PH has a reliable AoE size together hard CC. Some variety to this table would be really nice.
