You’re comparing an early access beta game to a game that was released 7 years ago and received multiple expansions and content patches. Of course, it has more stuff but to be honest more doesn’t always mean better.
Yes, PoE has 6 affixes per item but in reality, 99% of the items are trash because the system has too many types and tiers of affixes and only a very little subset of them are actually useful together on an item. You cannot upgrade affix tiers in PoE so if an otherwise good item dropped with a low tier affix you need (or rather high in PoE because tier power is reversed there) then that’s it, you cannot upgrade it. You can do that here in LE which is the best part of LE’s crafting system. You need to have life/ES in pretty much every slot in PoE, you need to juggle with resistances which usually means you need to have 2-3 resistances on most of your items which means 2-3 suffixes and 1 prefix are locked. The chance of dropping a good item in PoE is astronomical, that’s why you’re better off farming currency and buying top players’ failed crafts for a reasonable price. You can try to craft a really good item from scratch yourself but it requires an obscene amount of farming, VERY deep knowledge of the crafting system, and an insane amount of luck. Yet again, you’re better off farming currency and buy top players’ failed crafts. Buying items in PoE is like jerking off using a cheese grater, it’s rather painful than exciting. You need to alt+tab to a website, search for what you need then whisper 20 poeple to get an answer.
Regarding builds, PoE’s passive tree seems to offer an infinite amount of customization but in reality, there are a dozen notables and keystones you need to get for a build to work and there is always an optimal path to get them. Due to the aforementioned problems with items and trading, if you choose a build that is not mainstream and requires specific gear then you simply won’t be able to buy good items for it. There are like 20 different builds people are using in a given league. Out of those 20 builds, 80% of the players use 3-4 that considered meta. Half of those meta builds are not viable until you pour 20ex on them and become godly only after like 100ex or more. There are 3 ways to get 100ex in PoE: get insanely lucky and drop a couple of 10-20ex items and sell them; farm for an obscene amount of time; or illegally buy the currency for real money. Lots of people do the latter.
Check out Boardman21’s build compendium here on LE’s forums. The guy has more than 100 builds, there are some overlaps and variations of the same builds but I’d say he showcases at least 30-40 unique viable builds. That’s absolutely amazing given LE is still in early access.
I have 1.2k hours of PoE playtime on Steam but I’ve switched to the standalone client some time ago, so I’d say it’s more like 3k hours. I was usually able to build on a 20-30ex budget so I could build a very viable character each league but to be honest I’ve been having more fun in LE in that 70 hours I’ve put in it since I bought it 3 weeks ago. I have no intention of going back to PoE for the new league because LE feels much better for me at this moment.
Edit: another thought that just hit me regarding PoE builds. If you want to create certain types of builds (cast on crit mainly) then you need to know how the server works because if you don’t then you can pretty much halve your DPS by increasing your attack speed. Or you can spend 5ex on a belt with cooldown reduction on it but it does literally nothing for you because how the server handles internal cooldowns. I don’t mind researching all this shit, calculate thresholds based on server tick times to optimize my builds but to be honest a game should not work like this. You should not be required to have knowledge about how the game’s server work just to not screw up your build.
