Why? Mining is TONS easier now when you know where the resources are. I collected 10 stacks of iron + 6 stacks of nitrate just in 10 hours mining using an auger. At that site there is still tons of iron/nitrate laying around. At another site I collected 4 stacks of coal in a few hours. You said mining was boring before and that you preferred going around mining the surface boulder. I think traveling around just to find surface boulders is WAY more boring (takes longer) then staying in one spot and mining. You get way more resources through mining.
With surface boulder mining you are always moving around and opening the map, encountering things, discovering POIs and popping in to loot them and so on. It's a mini-adventure. In A18 I spend an entire day down a hole staring at a rockface and encountering nothing more interesting than the odd cave-in. No comparison.
True you gain more ore in A18 ( guesstimate about 50% more than a day's boulder mining used to give) but with the unbalanced MP gamestage you burn a ton more of those resource so it works out about the same. I still spend 2.5 to 3 days in every 7 on average mining to get enough gunpowder and lead for the group, except now I have 3 days spent in a goddam hole of boredom instead of 3 days driving across unknown areas of the map for boulders and having adventures.
If you can't see the difference in fun factor between 3 days boulder mining while having random adventures and 3 days down a hole then I don't know what to tell you.
Are you complaining because now MP isn't as easy anymore? Now you have to use more bullets? How about using traps, turrets, grenades, explosives, etc. Or how about using tactics/strategies? I found the molotov, pipe bombs and grenades are very useful. Learn how to group them up and aoe them.
Doing all that. 24 blade traps in 2 separate linked kill boxes. Still using double the ammo we used to. [Edit: only in MP co-op, SP is fine. This is an important point, see below]
If your base is being destroyed easily it means you're relying on your previous A17 knowledge.
Only our stop-gap living base that we always erect while we build the main kill base was destroyed.
A18 is a whole another ballgame and you should adjust/adapt accordingly.
Have you not listened? I have 2 games on the go right now, one single player, one multiplayer. Both are roughly on the same day (33). Settings were identical. My build plan is identical in both....live in a concrete box with simple defences while the proper kill base is built. Obviously we get the main base finished quicker in MP as we have more hands to build it, but typically the temp base handles 3 to 4 horde nights and always has.
There is no comparison now in A18.
My SP game is a walk in the park. I need to stress that. I didn't need to adjust or adapt from A17 tactics at all; everything going as planned and expected in single player; no complaints (except the mining). MP game....totally different story. Unbalanced combined gamestage is resulting in massively more ammo needed and destruction of temp base.
Sorry your argument of A18 sucks because they removed surface boulders as a source of resources and made MP harder isn't convincing.
Hopefully I've clarified things for you.
