Maybe it'll be different after the Q4 update, but right now I don't feel anything other than DDS is actually geared towards Exploration - I don't think that Fuel Scoops fall into that category and definitely not the FSD+1 size that explorers demand.
If FDev come up with a combined ADS/DSS and give some ships (not the 'Conda) a slot dedicated to it I think that would address a lot of the complaints.
Of course there'll still be people who want it all - long range, lots of slots, great visibility and good SC handling - but 'One explorer to rule them all' blows what little balance we have out of the water completely.
I think resolving the scanner issue would tremendously improve things. The problem is, Explorers have to sacrifice available slots for different types of scanners, whereas some activities that simply don't need them do not. Why should Explorers be the only ones to sacrifice? I mean, for all intents and purposes- even haulers don't have to, unless they choose it. Explorers simply cannot make a "choice" in the matter, you either have scanning equipment- or don't, which then means you cannot "explore" without it.
That's a pretty stupid design choice, IMO.
