I assume, u mean that with that price, you would be able to pull elgy and epic puk? If so, implement this asap.
Hm not sure, the legendary option has now been buffed, drop rates are similar to that of a prem box/pack, but l-m drops r slightly better, and e-m drops as well. So You can pay 2 million to get the equivalent of a slightly better prem pack. That guarantees you on average 1-2 legendaries.
Otherwise, the epic crafting hasn't been buffed.
For now just the common option has been buffed, so you can craft 1 common for 1000 coins. Currently that makes the best way to boost with base: craft 1 puk, and upgrade it using commons if its common, then use 3 common kits+1 rare+3 commons to get 1 max rare puk.
Besides that, you can now earn up to 75k from each base, however, the gold generation rate hasn't been increased a lot, so it takes over a day to fill up the base, whilst this is great, since you don't risk coming back to a full base, effectively having lost money, it is often quite irrelevant, however the production rate has also been increased a bit, so that's great.
At this point, I would recommend activating base, as a way to dump gold and get good legys. Just my personal recommandation though.
