He does that a lot.
There is a connection between war dec cost and grouping, to war dec the bigger alliances requires a deep pocket, 500m to war dec the Goons for example.
In effect the move towards larger groups was due to that and also the desire to become top dog, also a number of players were investing in the Merc business and were quite brutal about it. Then as content dried up as new players went straight to nullsec what was left was not interested in fighting, so the only real content was blapping idiots from nullsec alliances and that costs to pay for the content.
You see many null sec alliance players don’t bother checking if they have a war dec and bang easy kill, I had one mate bring his JF into Amarr and he suddenly wondered about the flashing reds, luckily for him he docked up. So I went in and got his JF out for him, but this is a key part of the war decker approach and it gets them a lot of kills.
I found some mercs were so desperate to find hisec entities that could fight that as soon as someone showed anything they all piled in on them, quite frankly it got silly and caused a number of promising corps and alliances to collapse and go into avoid mode.
Hisec is now really the indy alts of nullsec players in small corps that avoid this like the plague.
I kept my eyes on what was going on in the Merc area, as such I can’t really call them mercs, they are more like protection rackets now.
By the way the movement towards bigger groups and hub / pipe hunting happened before the watch list changes, some people refuse to accept that, but it had already happened before that was applied.
