Personally, the only two facts that bother me about them are:
1) They are on 4-5, a map that is already overcrowded with aliens... Needless to say what has been said thousands of times: now quests on there are near imposible EVEN in an outfit of 5...
2) Despite the fact that they are more dangerous than Sibelonites (they may hit lower, but they compensate on speed), their reward is very low... So, you are taking a higher risk for a smaller reward... Pointless, if you ask me.
As for the rest, like design, difficulty and so on, well, it is only a matter of practice... Kristallons also used to be hard for users in their times... Yes, even before the new AI... So, yes, in my side, only those 2 problems are worth mentioning...
And as for them being in X-5 maps... Hm, that may be an issue, actually... Many starter players hang in those maps... Putting an advanced alien makes more for an unbalance than a progress...
As a suggestion, it may have been better to put them on the X-6 maps replacing the Kristallins... Only the small ones, of course. After all, in that map, it is of no relevance how fast the aliens are: they will still be bothersome when hunting Cubikons, no matter what... May them at least do less damage, no...?
And since, normally, no weak player hangs in X-6 maps, anyone on there would be prepared to confront them with relative ease...
Anyway, this is just my opinion... I hope it proves useful.
The illusion is that they have invaded and we must drive them back, but this is impossible.
If that were possible I would pop them, but till then its grab an alien and get it to port, which is hardly condusive to creating a war game that forces people to be in the open and therefore open to attack.
BIGPOINT listen.. if you wanna make a good war game get the enemy in the open, I would suggest aliens that only frequent open areas but offer high reward, instead of things that chase you away....and only offer slightly more than a mordon
But guys (/girls) Look at the positives okay, if you go credits hunting with kristallons, every 5 mins or so, have a look around X-5 maps and you'll find tonnes of interceptors which are pretty much dead so you'll get rewards. This could give you and easy boost. However in 4-5, they are a pain. i have not been in there since i don't want to take any risks, but the annaliator thing looks very attractive, and im dying to have a go at it, but there are always npc's surrounding the port so either cloack, EMP ir die. Choose they all cost 500 uri (unless you have premium. Pirates are a (little) too fast. Maybe reduce the speed my 20?
