Enchantments Seem Weak

Looking at all these changes, and the new enchantments for jungle items, I've noticed a lot of them seem very weak compared to any item. The a/s enchant gives 50% a/s which is not much, along with an on hit that does more than old ff, but scales the same with monster kills, which are harder to get with stronger monsters with longer respawn times. The 80 ap and 10% cdr feels weak compared to something like rylais by a lot more than it should. Rylais gives 100 ap, and 400 hp which seems a lot more than 80 ap and 10% cdr, and it also gives a slow. I understand that these enchants are not supposed to replace an item, and with the jungling buffs it provides along with smites that can help outside the jungle in some, but some of them feel way too weak compared to real items. The cool passive that lizard provided and the tenacity on golem made it a bit more worth, but the only thing I see staying is the tenacity, and even the old jungle items were quite underpowered. I'd like it if they buffed some of the enchants with more stats and maybe increased the price of buying that enchant.
