After reading some of the reasons that several users wrote when voting for Poison as a primary typing, I feel that they really need to look outside the box when it comes to how our type selection will effect the outcome of our final creation...
Maybe I didn't make this clear enough in my last post, but, with respect to the two typings we have to choose from, resistances and immunities are irrelevant at this point of the process. Both types are rather good defensively and share a common weakness, so I feel simply stating that "Resistance to X!" is not a good enough reason to vote for a specific primary typing. I find this especially pointless because the secondary typing selection, which hasn't even begun yet, could completely offset the said resistance. Plus, the fact that, say, Poison resists Fighting, isn't necessarily better than Electric's resistance to Electric, so it is pointless to argue, at least at this point anyway, that a certain resistance that one type has over the other makes for a better utility pokemon. The point is, both types offer nearly the same amount of advantages, so their really is no point in using them to justify your vote.
The other thing I notice about people voting for poison type is that they argue that Toxic Spikes absorption is very good utility. While I will not argue that this trait is is a good asset for a utility pokemon, I feel it simply doesn't justify the vote for poison typing because we haven't even defined any specific roles for our creation beyond utility. There are several moves and traits in the game that can be labeled under utility besides setting/absorbing toxic spikes. Thus, in deciding which type to vote for, I looked for which typing would make a more interesting utility pokemon. This brings me into the main reason of voting against poison typing -- Several poison types already have access to the the utility of Toxic Spikes setup/absorption, so why the hell do we need another one? On the other hand, Electrics have been built primarily offensively and have very little to offer in the line of utility.
When I look at this poll, I view it in terms of the very purpose of making concepts -- the very purpose of this concept... How does our creation contribute to the overall metagame of pokemon? A poison type, based on the reasons posted so far, would do very little, but a pure utility electric type would be far more interesting and have a more profound impact on the game. It doesn't have to be game breaking, but it should at least stand out. With all of that in mind, electric is a much better choice, and I would be ashamed if the community would put the opportunity of making a pure utility pokemon to waste and vote poison.
