Damn
Nice ideas man
For ghosts unlimited exp. I`m so corrupted by this game, that i got stuck in no loss play and never thought about it
Ghost soul drain was broken since start of game, and i wondered how to change it so it resurrect % of killed troops, not % of dmg dealt. It seems wrong to attack 1 dragon not kill it, and gain some 20-30 ghosts. WTF ? Same as your comment, rise new units from phantoms.
For phantom marauder/goblins gold search i knew, and it`s great way to get early gold (after certain time, usually i get millions of unspent gold so it never was a real problem). It`s much easier with spell gift in KB-the Legend thought but same mechanic basic.
Infinite runes same as for gold, but allot more time wasted.Only question is how long are you ready to spend in same battle.
All in all, great thoughts. And since this game got published, players kept trying to figure some broken strategies.
Have fun, and take care
