I leave it in the middle, it’s everyones choice and decision.
I don’t place towers near the gate, according to my opinion if someone manages to destroys my towers and beats my troops in time, then the raider deserves to win. For me it’s a sign, improve your defense, upgrade your towers, they aren’t good enough.
Sure, it can be frustrating to miss a tower, but I always blame myself when I miss a tower. I have no problem with towers near the gate. For me it doesn’t matter, I just learned to check base plus tower location before I attack. When someone designs the path in such a way that canons can destroy the gate from another path, I either don’t use them or I use scream to pull them away from there.
When I see towers near the gate when I check the map and when I spot them I try to remember where they are located. I know that I need to adapt my strategy at the end and try keep my sonic blast in reserve at that moment, but I only use that strategy when I arrive there with enough time left.
When I have not a lot of time left, the defender actually should have used those towers earlier on the path, at least I would have been slowed down more and would probably not raid succesfully. That’s his mistake, so it actually costs him skulls. some wise defenders make sure to place a tower with tough barricade just before entering he castle gate space. Even there I refuse to use a Sonic blast when I have enough time. I know I need it to destroy remaining towers, so I let my troops destroy the tough barricade if it’s placed there.
When I arrive with more than 30 seconds left, I know I have more than enough time for two sonic blasts. Most time the towers near the gate are firebolts or snake towers. I run a littlebit forward and destroy the towers at one side with a sonic blast (I have extra SB perk, so towers will fall, don’t touch the gate, it should be not damaged!), summon a mummy to distract defending troops and run backwards to use scream to stop my incoming troops from nearing the gate and use shield to protect them when defending troops are firing. In the meanwhile my sonic blast is reloading. When troops start to move forward, I use my blizzard to cool down or whipe out defending troops and run to next position between remaining towers and activate sonic blast. This time I do hit both tower and the gate. Job cleared, 100% raid.
Even in situations where both sides have three towers (firebolt/skull, snake plus firebolt) this tactic works.
I know it can be frustrating that players place towers near gate, but finding a tactic to overcome that problem is also fun. Like I said, I only blame myself when I don’t destroy all towers.
Before I used this tactic, it was more gambling than wisdom. For example both sides have firebolts. Destroy one side, run to the other side and scream and hope for canons or range troops to destroy the tower before gate. Often I failed. With new strategy, it even becomes fun.
