Johnny, I target different species. Sometimes I have spells on particlar fish - for instance I'm Perch mad at the moment.
This afternoon I'll be having a couple of hours trying to locate some big Perch but tomorrow I'm off down to the Trent. I shall be fishing for Perch in the daylight and will switch to Barbel after dark. the tactics and tackle used will be completely different.
I still consider that to be specialist angling. People can call it something else if they choose. That's up to them.
Beecy, just do what you enjoy. I still have the odd session where I fish for whatever. Last week I fished with an old school mate and we just trotted maggots. We caught Barbel, Chub, Roach, Perch, Bleak, Bream and Gudgeon between us and it was enjoyable.
I don't fish this was often but it's nice to do it now and again.
