I like to compare this update to what we had previously.
Before EGP3, an attacker would have to attack the tower, hold it for long hours, and then reap the reward off the Sites, this was in anyway not convenient for any attacker. After EGP3, an attacker simply gains the rewards after taking the Site.
Even with the new update that will make large clans take longer to heal and drain, wars still remain predictable and boring.
In less than 1 hour the maps will be protected.
What's the fun in that?
In the past (2013-2016), attackers have toppled large alliances through attrition, as there was no way for defenders to corner attackers and throw them into Dinoville or simply stop attackers from attacking.
it was not necessary to have DDs to revive.
Your dinosaur could revive with full life.
the maps were not closed with a single path.
PvP (dino vs dino) benefited experienced players who played well, so it was possible for a small group to defeat a larger group.
If the attackers wanted, they could bother the defenders all day long, this is what caused the alliances to weaken at some point and fall into the hands of the attackers.
In other words, it was fun to be an attacker and compete with the defenders.
now without these mechanics that gave players freedom, being an attacker became a punishment.
I'm not saying that the game had to go back to exactly how it was years ago, but i think that it could be possible to make an update that could be simpler and more fun than it is now, all the freedoms that players had were removed and will now be removed one more (being able to attack whenever you want).
The great imbalance between defenders and attackers that began slowly in 2016 (with the closure of maps, and other mechanics that were changed) and worsened with the changes in 2019, goes far beyond the drainage and healing mechanics.
How wouldn't the big alliances become extremely strong, if when they kill you, you are forced to revive on another map? If you have no option to escape, as there are no alternative paths on the map? If you die many times, will you be forced to put on protection and go hunting, so you have DDs to revive? In a war, the attacker always dies many times more than the defender. So it's obvious that it's not worth being a attaker nowadays.
This game needs a little chaos, after all, the main fun is the battles, but how can you have fun with so many limitations?
This update may balance things out a bit, but it will be far from fun.
