Well...I never could get Pekkas to work...
They're a bit disappointing. They can't tank, can't stay on target, if they wander into a Tesla they're fried, and they make lousy CC troops. There are better ways to spend 25 housing spaces and 42,000 elixir.
Pekkas may have been the Ultimate Rage Super Level 10 Mac Boom Diggety when the game was first released and Town Hall EIGHT was the maximum, but in a world of now four, level-7 Teslas; three level-3 x-bows; the Big Troop Killer, Inferno Towers; and the Dark Elixir Army, there's just no room for the PEKKA.
So, yeah, maybe revamp/restat/reconsider/remodel. This is the MAX LEVEL barrack troop, man. From the day I first loaded the game and made my first Barbarian, I was looking up to this thing, thinking how awesome it would be to finally have one. It's LEVEL TEN, it's supposed to rock harder than the Dragon.
I'm Town Hall 9 now. I use Dragons, people who raid me use Dragons. I rarely see PEKKA. Know what happens to people who come at me with PEKKA? They leave my village with no stars, negligible loot, and curses about PEKKA not living up to expectations.
