Placement of traps/turrets
Is it best to simply create a field of 15 lvl 10 turrets, or is there a benefit to placing a trap here and there. Assume you are going to be attacked by high level players, with large armies, so we are not talking about deterring mid level players.
I would think a row of turrets delays troops the same as traps would, but have been told that may not always be the case. Further, I was attacking not long ago a city that had one trap placed in each row, and I held longer than I expected. One row took 2 rounds for me to get through, despite having more than enough cav to get the job done on one turn.
So in the end, I guess what I am asking is (a) if it is better to place some traps on the field with the turrets, and (b) if so, how would you lay everything out.
Any advice on the topic is appreciated. Thank you.
