My troops,
Not quite 3 years f2p.
If I had concentrated on the first troop, I could have lvl.30 in all colors.
But I fight with 3- or 4-stacks in war, occasional a mono attack, so I went for lvl23/17/11/11/5 in every color:
Sorry mate,
but I won a lot of EHTs and ETTs in Challenge events. I use ETTs only in Towers and do not keep crit and Ninja troops. HA6 runs without pause for feeders.
I use EHTs only in seasonal Portals, and a few gems too, because the chances are there a bit better (1.2% compared with 1% in other portals).
