Right now the wiki has one article for each elemental type of area of effect grenades: Tesla Grenade (Shock) / Cloud Grenade (Corrosive) and Burst Fire.
The three should be merged into a single article called "Area of Effect" or Area of Effect (Grenade). AoE grenades are the only exception where each element has its own page (for example there isn't a page for fire MIRV and other for corrosive MIRV) and even if the effect of Tesla is slightly different to cloud and fire burst that can be covered on a single article.
The game makes no difference between them for counting toward the AoE Grenade challenge and the Payload (which determines grenade type) is the same for all. The only difference is the element accessory, and "Tesla" "Fire Burst" and "Cloud" are the respective nomenclature for shock, fire and acid, which means that the three are variants of the same AoE grenade type and not separate types as they are stated on the wiki right now.

I ask the wiki community to decide and vote with a reply here if such articles should be merged or not.
