Is it just me, or do raids seem to happen way more often than before the H&H update. Before the update I could go hours without a raid, and sometimes I would get two raids quickly and then go several more hours without a raid. Sometimes I would go 30 to 90 in game days without any raids. However, after the update it seems like the chance for raids are almost 100% instead of the 20% default. Yesterday I played around 4 to 5 hours and had 3 swamp raids and 2 troll raids all within that time frame. Today in just a few hours of play time I had 2 troll raids and 1 swamp raid. The default is it checks every 46 minutes and you get a 20% chance of raid after the check. However it feels like you get a raid every time it does a check. Its to the point I am having to add a mod just so I can build and do some things without getting raided so often. Devs really need to check this out and make some tweaks because raids are becoming more of a nuisance than a cool mechanic at this point.
