It negatest the 2 PPC/LL limit (in a sense making it a 1-weapon limit), while punishing you for chaining 2 groups.
If you macro a 0.26s spread on shots 4 times in a row, or you macro a 0.51s spread on a pair of grouped shots, the perceivable difference is negligible. But one option allows you to to land 20 + 20 points of pinpoint damage in 0.51s for no extra heat while the other punishes you for firing 4 PPCs (and is in fact a 10 + 10 + 10 +10 pts pinpoint in 0.52s). With six weapons this is exacerbated even further.
Not only does this solve jack poo from the macroing perspective, it also confuses the players even further by adding yet another level of complexity on top of this atrocity and results in crazy things such as ghost heat penalty for a pair of AC2s (macroed or not), unless these are group fired,
On a side note, I finally understand why I kept getting heat spikes when firing my 3rd LL more than 0.5s after the first, but with a less then 0.5s break between the 2nd one one...
