By the way it took us a while to get to this point where nothing is OP at the top level or nothing seems that way currently. If you haven't forgotten we just went through 5 big rebalancing waves where several overused and oppressive mechs got NERFed so that builds could diversify.
We have yet to reach that point in early game. And it's far from true that nothing is OP there.
And to explain to you how let me tell you I know that there's 3 criteria that determines if something is OP. Those criteria being as follows:
Is it overused?
Do people using it win significantly more than those that don't?
And is it fun to play against?
The equipment needs to meet both of the first 2 criteria or can just meet the last one or all 3. And seeker meets all 3 at low SP. Let's go through the criteria for seeker at low SP, shall we?
Is seeker overused at low SP? It's hard to tell. Because it's a camping mech and using it is widely regarded as dishonorable its one of those mechs that lots of people say they only use it against other campers. So perhaps a good chunk of them aren't lying. But fhey have it in their hangars. I'm sure plarium still counts that in their stats.
Do the people who use seeker win more than those who don't at low SP? I know I lose to it more than I do against people who don't use it, with the exception of other camping builds. And despite everyone's preconceived notions, I'm not a noob.
And finally is it gun to play against at low SP? Well does it sound like it's fun to play against at low SP? I've complained it has full map coverage on many maps with a freaking teleporting ability and it's got no exploitable weaknesses its damage near matches 32 max energy with the damage boost and it gets a physical shield. Oh and did I mention it's really good at taking advantage of lag and oh did I mention ITS FREAKING INVULNERABLE DURING ITS TELEPORT MEANWHILE IT CAN STILL DAMAGE YOU?!
What is mid at high SP a minor nuisance can sometimes be instant death without a hope of reacting from anywhere on the map at low SP because of lag and you can't "learn how to counter" lag. It doesn't even need to be a ton of lag. Every internet communication has some lag. Seeker benefits from lag more than others because it has a lock on ability which initial lock ons usually take a bit but switching is near instantaneous. It only needs a little lag.
Being able to get an instant kill anywhere on the map without having any counter play or exploitable weaknesses can't be construed as anything but overpowered.
SP tanking with seeker is OP so devs need to either fix SP tanking, which devs seem to inept to see the obvious fix in giving items their real power ratings, or NERF Seeker or both.
