I don't agree with any cons except for that your 'unbreakable' achievement will be at one star for a loooooooong time.
The pros outweight the cons by such a large margin, it's almost surprising how many players in game have not clued in to this tactic.
You see these level 45 TH9 players painfully push their way up to crystal and have their TH in their cores, that's a DOUBLE fail for upgrading so severely premature, and for pushing cups so high that all they can do is snipe and if they're lucky enough to come across abandoned bases, they get a bit of resources. :confused:
