The science system has been overlooked for too long. With each new implimentation of new content, it seems that the science system continues to degrade. several content patches over the past few years have slowly made the specializations less worthwhile or obsolete. One of the most disappointing is the original release plan.
"RELEASE PLAN
The Science System will be released in a couple of batches. The first release will bring full production chains, tutorial quests and help windows. Depending on your test feedback on our official test server, the first release might also include the Geologist’s Skill Tree. More skill trees (explorer, home island, military) will be implemented later."

While it only took a couple of months to implement the explorer's skills from the introduction of the science system and the geologist's skills, it has been years, and we have not seen new content concerning the military and home island.
Some examples of the science system being overlooked, obsolete, and less worthwhile are rather apparent; however, I am sure I can not name them all or list them all. The explorer skill, Sophisticated Pillager, will not work with fairy-tale adventures, mini adventures, co-op adventures, or scenarios.
Streetwise Negotiator is obsolete when compared to the other skills available.
The game mode has shifted with regards to iron production with the implementation of pvp as well as the adventure loot not dropping weapons. All build-able mines except the iron mine can have fast mines. I am not pointing towards either addressing if iron mines should be fast or not; my point is these skills were made for a specific point of the game. While it is impossible to consider the future because it has not been written, the future can consider the past.
Science should be the future. For example, I heard "rumors" that the developers do not like us using recruit armies to take the blows that protect the more expensive units. The reason most of us use them is due to them being more efficient to produce. That would change if we had skills for the military or the island that would make those units more appealing.
I love the science system, it really gives us an opportunity to have different goals for our islands and the means to do it. I look towards the test server and see the science system is not being considered right now, but I would like to see more skill trees in the future and not see it go to ruin or to cookie cutter specs due to the ever changing game.
