With 10x harvest and craft, it would just turn into another builders haven. If anything, 10xp, 1x harvest, 2x as long to craft. the idea is not to have people go into build mode all the time and to be more about fighitng back and forth. Get on, get leveled, farm and build a 6x6 homve base. Then defend and fight as necessary. Armor is relatively cheap compared to building cost in general.
1 set of medium with named armorer costs estimates with a T4 Armorer (epic Flawless medium)
140 ichor
70 Gold
140 Silver
140 Oil
70 thick leather
140 Leather
10 Twine
100 Iron Bars
70 Rhino Hide
So getting to level 60, finding a named armorer, and killing about 6 Rhinos, running 10 fish traps, mining 5 or 6 Iron Spawns, picking 20 dry trees, swimming buccaneer bay and grabbing 10 plant fibers will net you a epic flawless armor set. DLC’s would be premium on these servers to guarantee your PVP build style. And oh yeah, grab a relic hunter and run a few quick boss runs to get some legendary weapons among other things. Building would be a back seat to farming for fighting. Not necessarily a blitz server, but a dedicated server for fighting and not over building for once. Again, keep the other versions. If the “new” server type brings in players, it is beneficial to long term goals. Eventually, the player base will be only PVE, and as good as that sounds for some, the numbers show that styles player base is not growing as quickly as the combative players are leaving.
