This is absolutely the right thing to do. Done similar though not as drastic on power. Changes the game completely and as far as I can tell in an entirely positive manner.Havent been able to play much recently, but i finally got my fantasy test franchise teams created and drafted. I went through and amended attributes (detailed below) Only played a session and a bit so far in sydney with the Sydney franchise playing Johannesburg. Having reduced i was worried teams wouldnt be able to put up a big score on the flat wickets but so far joburg 70/1 and batting well having won the toss.
Judgement: reduced to 1/2 for tail enders, 5 for mid tier batsmen,6 for elite batsmen
Power: 1/2 for tail enders, 5 for everyone else
Every other attribute was reduced by 2 from the big ant default attributes , bowlers attributes weren't touched, gameplay has been very fun batsmen can hit fours and still hit lofted shots but the lowered judgement just adds more dynamism to the game, lbws feel more achievable and i find you can set them up too. Will post with screenshots when first innings is complete
