If that is the case, that the enemy is too easy??? Maybe you should make access to alien tech more difficult, as destroyed alien tech gives no research option.
And alien interrogation could also be on a broader level, as there are pilots and engineers + other specimens, that might yield usefull information.
The most impressive part of X-COM games were the research and the unknown outcome... and how long it would take to make a breakthrough.
Here; it is on an exact timescale, which is another bad choice, when you are dealing with ALIENS!!!
Or has the meaning of "ALIEN" become so trivial, that the imagination has left the game completely???
I am very disappointed.
