I know there was a topic about this before, but I cannot find it.
I also know this is mostly a problem of the higher regions of PVP, but still ...
I cannot finish 3 battles in PVP before my shield goes up again, whenever I come near the top 100-200. Sometimes I cannot even finish 2. I should not even try to change monsters or relics for different defences, because once I am done my shield will be up. I should not even think of the best strategy, because my shield will be up again. I should not dare taking longer than 2 rounds to kill the enemy, because otherwise ... my shield will be up. I don't want to be rewarded for killing triple Warmaster bases in a long and difficult battle by just having my shield up again. PVP should not be designed to cater to the fastest kills or slow-to-kill defences. No one is playing with life based strategies on attack now, which is a pity. This situation is even worse in L II. Cannot turn your behind before you are behind a shield again.
Please, give everyone at least 10 minutes to normally finish their attacks. Make PVP playable as it should be played, at all levels, with 3 undisturbed attacks and room for any kind of strategy.
