DOnt make it 50 yet, seriously my friend, ive had exactly the same struggle as you, was lvl 68 str with 40 att. Its not worth to train 50 att yet because there is so much concurrention at your level + every1 off your level has tactics to not die from maulers. Ive made a bad choice at the time too. you have to be 75+ str for ownage, tho if you get 60 attack now yould own, but ur hp would suck hard. Just my experiences.
