Some cone-based targeting was changed so that it calculates from a center point rather than a specific facing. While this affected nearly every entity in the game, it only significantly impacts very large entities. A side effect of this is that there aren't as many "safe zones" from Borg Cube torpedoes.
Thank's for clarifying! So it was an across the board change, then I can understand that, so then can the borg eventually get an exception to reflect more like how they were before? I'd be so happy if that could be done, it's my only major issue with playing STF's now that I never had before. This would go a long way to restore balance.
