Back in the day of nanobot trade there was more to picking targets. You could go for their top gunners to deny chance to shoot or go at their worse dodgers to burn nanobot supply.
Nowaday its simply targeting their best gunners first and removing them from the fight as soon as possible with no way for the opposing force to counter it but to do the same and hope to kill your top gunner first.
Id say things have been brutally simplified and as someone who usually is first target unless flying alts I don't really enjoy it much.
Downside to nanobot trading is the fact capitals can feed snubs with nanobots and that makes capitals involving themselves in snub brawls really cancerous.
What I would consider best is if cap and snub ships use different kind of nanobot so that won't happen. Then we get the extra tactics of snubs without the penalty of cap interference.
P.s. I'm throughoutly against removal of regens and having them added to hull for snubs.
