Insta troops are very usefull in offence. They’re absent in defense. I thought a lot 'bout implementing instas in defense. I didn’t got any ideas. Implementing insta troops is very hard but what 'bout implementing insta boosts. Yes Insta boosts in defense. It’s very simple. You arrange them in ordinary fashion. Just enter the guard and arrange them. When the boost is active they become invisible in defense. And when the king is near they turn to visible. (They won’t attack troops if they’re invincible.) The same application goes for mummy. (No boosts required for mummy since mummy is already instant spawn.)
The next thing I wanna say has no direct connection with this topic. I’am talking 'bout gargoyles. Gargoyles are the most useless troops in RR2. Making them insta without boosts and reducing the attack a little bit can make them useful and balanced I guess. If they do, then the same insta application goes for them. If you find a solution in implementing the insta troops (the troops which your friends gives you) then please tell to me.
Hope you like my idea, thank you
