I wanted to bring up something that’s been bothering me for a few months - admittedly I should have sent this ages ago, but better late than never, and the night of the new PTR patch seems like a good time.
The Hydralisk Lunge tooltip has a grammar mistake: “The Hydralisk Lunges forward, greatly increasing it’s movement speed for a short time.”. It should be “its”, not “it’s”, since the latter is always short for “it is”, whereas “its” is the possessive. Similar for the tooltip on the Nanomuscular Swell research on the Hydralisk Den: “Allows Hydralisks to use the Lunge ability, greatly increasing it’s movement speed for a short time.”, although in this case I’d suggest “their” rather than “its” since it’s talking about multiple Hydralisks.
At the same time, can I suggest changing their icons form Assets\Textures\btn-upgrade-zerg-frenzy.dds to Assets\Textures\btn-ability-kerrigan-wildmutation.dds? I feel the orange glow in the icon fits the appearance of the ability better, especially for a spectator (where the Frenzy icon just looks like an attack upgrade) plus red/orange tends to be the preferred colour for late-game zerg upgrades. Sure, the head is that of a Zergling rather than a Hydralisk, but most people won’t know that. It will very likely be clearer for spectators especially.
(Look up the "Wild mutation " topic on the StarCraft Wiki if you want to view the suggested icon… or view it in the editor)
