It's been a long time since I check this thread. My progress:
1) Yes, I've several accounts at 200+VP , XP50-55 ranges, HQ20-21
4x diamond chest maximum for idle accounts. Sometimes the 5th one comes out immediately after you clear the map.
2) One super duper 20+VP
, XP48, HQ19 and no, you cannot hit NPC
as this will gain VP due to the +2. What you get and what to do is:
- Sgt Brick only, nothing else.
- No War Factory, no imitation game, cannot attack NPC at all.
- Only Hammerman strikes back on every Monday, but not useful to gather resources. You don't need to build any proto either, as literary no one will attack your resource bases after certain levels.
- Only both Dr.T Tropical and Volcano, twice a week (Wed-Thu, Sat-Sun). Boost reward statues.
- Wait for mega crab or turtle event for a lot of loot.
- Join active TF, this will give diamonds and resources on a daily basis.
- Collect from 3x wood and 2x stone resource bases only. No iron RB.
It's very slow once you reach mid 40s XP, as each upgrade may take 2-3 weeks or longer to accumulate.
