Turtle power ruins games

For me it really ruins the game when 1 player can sit in a base piled with all of their specialists and hold off an enemy who has 10x the production and unit cap of his. I have had multiple games where a player get's a sentry with a pile of specials and makes it impossible to finish him off without pulling so many troops off of my borders that I lose them. This game is about strategy and there's no way to counter a turtle unless you get a navigator, pirate, assassin combo which can take multiple days of waiting for the right specials and even more time to get them in position. Choosing to ignore a turtled player just turns them into a ticking time bomb, they will continue gaining specialists and building up troops (up to 150), wait until you are preoccupied fighting another players and then blow a giant hole in your front line.
Some ideas for nerfing turtling:
#1 Cap the number of "active" specialists (specialists who's non global effects happen) at a base to 5 (counting queen). This would help by greatly diminishing the effectiveness of a pile of specialists while turtling.
#2 Having a minimum number of bases required to gain new specialists (3 would be a good number) would allow an attacker to strategically shut down his opponent's growth (which makes sense if they have only 1 base left) giving the attacker the opportunity to slowly wear the turtling player defenses down and not having to sacrifice their other fronts to do so.
#3 Increase the number of choices of specials to 4 so that players have an easier time drawing nav+pirate+assassin.
