The way I see it is you could:
1. See every attempt to not fight zombies on horde night "cheesing", And try to fix it.
2. Allow bases to be unbreachable, but not balancing the cost so that there would be no way to repair the damage by next BM (This would mostly apply to SP)
3. Making the top tire materials unbreachable or easily repaired.
4. Balancing ammunition cost for turrets so they can defend a BM and be filled up to the next one.
If 1&2 are true. I think we will start seeing more BM combat bunkers, away from the real base. Because there would be no purpose of building a base with bad ass protection since it would be to costly to repair in time for next bm.
The combat bunkers would basically function as a stationary temporary armor.
If 3&4 are true. It would give endgame or top tire material a real purpose.
On the other hand we might also see some BM combat bunkers with Lower tire materials for those who wants to go 1 on 1 with the zombies. Or maybe they will decide to put points in other perks than top tire materials?
Im not sure more settings are necessary. I mean If I want to have a harder play through Im not going to build a 20x concrete wall filled with turrets and then complain about zombies not breaching.
Ill strip down butt naked and face those bloody dead heads with my FISTS!!!
And a side note: "take a nap" is not what I think the ppl who are voicing these opinions are doing. Mining, building, cooking, repairing. Basically playing your game is what I bet they are doing.
"taking a nap" and logging out is what i think ppl WILL do if no place is coincided safe....Well AFK is
