I dont personaly agree with having invulnerability at lower dfs
Becouse that only benefits multi accounters more

The reason why you can't build t20 stuff in Earthforce Space is so you can't build amazing things without being killed. If you want to build better stuff you need to either get with a strong team so you won't die or build strong enough to not let players be able to wipe you easily. It's bad to have pirate teams building expensive things without having the threat of the teams they assaulted taking them out. Also Wild space is the only place you can own galaxies (besides those few special gals) and you can't PvB without owning a gal so that would enable Pirate teams to own an unkillable gal so they can kill newbies with ease.

What content are you referring to?

I think you are misunderstanding some basic game mechanics, perhaps because you haven't built in three unis. For over a uni now, bases have come equipped with basebound X gear. This means that you no longer need to build base gear to have bases. It also means that if you are unlucky enough to lose a galaxy, the cost of rebuilding elsewhere is not very high.

You can build a decent gal of t16 kits. If you have a team of ~2-3 people who leveled a few of their alts, you could have 5 t16 kits for each player, and the rest be used for ExE slots for the planets. Go like 4 t16 hps, 1 SL t16, and the rest for dps with grem drones and the ExE having weapons/hps would allow the gal to defend vs medium attacks. The main cost would be the augs, kits, SL, mags/shield trans, OLs and Overchargers. Doesn't have to be dem/ada kits can be lac t16 kits.
If an endgame team blows you outa Wildspace, then either politically you angered them or they are being jerks which some other teams would defend you (like RF).
If you want help with base setups I don't mind helping.

1. Bases come with basebound Tier 1 gear. Losing the galaxy is not crippling as it was in prior times.

2. Bases come with capability to build Tier 2 and Tier 3 version gear. Adamantium gear is roughly equal to Tier 1.5.

3. Bases come with ability to build powerful galaxybound permanent drones. Platforms are damage, Defenders are heals, and assault are mobile drones that follow the owner around and have half the range of Platforms.

4. You can get Junkyard Extractors, Extensions, and Hydroponics if you really don't want to invest in proper industry equipment. You should (as they are a different item altogether) be able to use Junkyard and normal, etc. Extractors at the same time. Junkyard gear is basebound once equipped.

5. Bases and Permanent Drones have a recoil cap of 0.5 seconds and have stupid damage per hit. The damage per second is unchanged.

6. Being on a team helps a lot. Granted a few of the teams listed above are solo one man teams, you don't have to (and it's heavily discouraged) to try solo building. This is an MMORPG, emphasis on the MMO part. You're expected to group up some of the time.

Which that is Earthforce space. You build in there an nothing but ai can attack you, which any ai in there can't dent an adonis kit.

Now that pretty strong termites have been given a test in Wild Space, I would be willing to discuss putting them in EF Warp 2 and expanding buildable space there. That would give players a chance to take the training wheels off a bit while still being immune to BvB.

I agree with some way to allow teams to not get killed if they build in ws w2, or w1. But it shouldnt be permanent (like a month or so of invulnerability would be more than enough) and if the team takes agressive action against other team, they should loose that invulnerability

Yes, but at least they would have had some experience building against tough opposition (the new termites are pretty strong).

What sort of experience are you looking to get in this new safe environment that you can't get in ef?
