1. Devs don't have money to pay for other developers, especially not 3k, if they had a lot of money they could work full time on the game, which I doubt that they currently do.
2. Problem with default client is not completely the lack of time that the only actual coding dev of this game has, but also opinions about devs not wanting some (most) of the custom client features into the default client at all.
3. Actually I think APXEOLOG once offered to code a new better client for the game, but devs refused. (Or was that salem, oh well)
I highly doubt that investment of few thousand euros to hire somebody to work with the client for few months would ever pay back. And who knows, maybe romovs has good career and a better salary in his current job so money wouldn't be a great incentive.
Also optimizing the client is not an easy task because that would require a lot of work from loftar with what he has been doing for last few years or so or a complete rewrite from scratch, but
it's too late for that now.
Best way to get better client is to learn swedish and programming, then move to sweden, find out where jorb lives, then hang out around the pubs near him and hope that he pays a visit, then attempt to befriend him. I think he posted a megathread with links to wikipedia articles of things that he likes, so you know which things to talk about with him. Then make suggestion about helping in the development efforts of the game, and in no time we have a new, improved client.
