In regards WH farming it is correct that if your multiboxing it's not worth farming C1 and C2. C3 might be a good training grounds but you'll outgrow it quickly as your alts get more SP. Generally in a C3 you can make 40 mill every 10 minutes in a well fit Tengu since your main can fly a drake already it's less skill time to train. Warp to site, pop everything, bookmark the site and move on. The signature is removed from scanners so when your looting and salvaging you'll see probes so you can react accordingly. I would use your alts cloaked for eyes and ears on other WHs that are present. Once you can fit the proper 5x Domi setup I it would be time to move to a C4 with a C5 static if your working alone or join a larger WH corp in a C5. By then you'll have the opportunity to train your alts into 2x Moros, 2x Archon and 1x Loki. Maybe by then you could add a booster alt that can also salvage sites.
