tl;dr: Base shields take a lot less damage than they're supposed to.
Long version:
My legion have recently started taking on tougher bases from larger legions as opposed to the smaller and glassier bases that we've done since I joined. A welcome change for those of us with beefier ships, as it lets us put all those excess stats to good use. Shortly after this change, we knew something was wrong with the damage we were dealing to bases. We've called off several attacks because the damage we should be dealing and the damage we're seeing just don't match.
As some of you are already aware, this isn't a new problem, but we've since discovered that it might be a lot worse on base shields. In fact, the problem might lie only with shields, and not base hull at all.
To prove my theory, I logged the total hitpoints of an enemy base each second for about 90 seconds. The first minute and a bit of this was when we were hitting the base shields, and the remainder was hitting base hull.
I compared each hit to its last hit to get the difference in damage between hits, and I also took the average over the last 3 hits to reduce the impact that latency would have on the values between each hit.
As you can see below, right around second/hit #65 (which is when the shields became fully depleted), the damage we were dealing increased by a fair good chunk.
You may think that this sort of behaviour could be attributed to people not hitting during the shields, and only hitting the hull, but with the consistency that we see shields taking a lot longer to deplete than hull, it is likely not the case (around 80s for 200k damage to shields as opposed to less than half the time for 200k dmg to hull).
Thoughts?
