Yes.. I have also noticed this. I thought that the Delhi Capitals were a bit better, but that perception was shattered yesterday. Or it may be due to the fact that the teams are asking their best batsmen to move up the order? In T20, getting a good start is very important. And secondly, some of the players who did the fireworks towards the end of the innings (Hardik, Pollard, Russell, Tewatia.etc) are not in their best form right now. And finally, there may be something unique with the pitches in the UAE, that makes things hard for the batsmen towards the end of the innings.
T-20 format is considered batters playground so i wonder if ICC wants some tweaking with the pitches for upcoming WC? Considering spectators do love watching big scoring games.
