yeah , being in D.A vs Being in a number 1 k tribe in world 4
I can say that i think that your just as safe being away from tribe members as you can have P.A's .
Now being in a tribe however you are all close together you can receive support quick but then your crowded in with a whole bunch of players lowering your chances to grow
Example : I was in Teams surrounded by Team Mates being world 4 my first i was learning but after i learned dhow to play everyone had already enabled all the good villages and i was left with few targets and i grew very slow.
How ever being in elei grew at a much faster rate although not as fast as I'd like but still considerably faster than before. simply because we were spread out and that's not bad because if your at all good you should be able to defend from attackers cuz getting attacked it part of the game.
Of course i could be way wrong
