Lord Draconian, you could build that blue building when the Orcs arrive.
The one I got is Elemental level and right when I have decided to add another res. Oh the temptation to just throw it in the line and reap the extra rank points... but I'm not doing it, besides that I just don't want a permanent blue building it would also indicate my acceptance of the fact that their lazy coders took the easy way out on the rebalancing and just changed the numbers rather than write a more well thought out upgrade code that didn't give the 'overpowered' buildings as much of a bump until they self balanced at the upgraders discretion. i.e. They would have became outdated or the player would have to decide whether they wanted to upgrade it 4 or 5 times to get it back on the rebalanced track with very little gain in the interim. I do not accept that, they should have coded an entire self adjusting rebalance rather than just do a hatchet job on the existing code because that was easier. So yeah, no blue building for me even though it put's me at a slight disadvantage to everyone that places it, something I further disagree with, a band-aid fix to a hatchet job rebalance shouldn't be near mandatory lest you incur further penalty than the hatchet job itself inflicted. But alas I would expect no difference, I'm fairly certain the coder team is just one of the dev's cousins or something. The dev's just set around dreaming up lackadaisical ideas without any actual thought to the long term or how anything will effect anything else and the coder does not have the skills to rectify their artistic minds with the reality of code relationships so is left with only trying to slow a constant downward spiral of patches that gets ever closer to game breaking bugs.
So there is that and it is what it is and I have came to terms with it BUT worse than that is adding prizes to events after the fact. I quit the previous game I played because they changed an event in the middle of the event, the only thing worse than that is changing it a week after it's over.
They seriously need to blackboard their plans and think them through, then discuss them with a decent coder team and rework their plans based on the realities of coding, then alpha test it and rework it a handful of times, then when they are convinced they have it put it into beta and spend a month actually paying attention to the feedback, then rework and rebeta test it a couple of more times THEN go to live with it... Instead of being like what I can only imagine is a couple of half baked idea people saying,"Duuude I came up with a new thing, call your cousin that kind of knows coding and let's spend a weekend throwing it into the game regardless of the repercussions."
