The ring is an incredible weapon, however Lantern's miss those speed feats that other DC heroes got,
Nope, Green Lanterns have on panel nanosecond reaction feats and a solid record against speedsters. You pretty much don't know what your talking about=)
many comics show a different picture
plus Lanterns forcefields have been easily shattered/broke in the past and when you get in close and down and dirty these humans with green trinkets and humans are not very durable
Wrong,t he only time their natural durability becomes a handicap is for plot convenience while facing street level or vastly out powered competition(this becomes a complete moot point when you consider that despite not having this weakness, heralds also under perform in a categorical fashion against street level opponents -Spiderman v Firelord, Acme brick v surfer, surfer v armbar - ).
Green Lantern durability/auto shields feats are EASILY on par with top tier characters - -
Your claim of Lantern having exploitable durability is unsupported and ridiculous.
Its well supported
most of the Lanterns featuring in DC are one with human levels of durability and once you get past a Lanterns shields they are toast
Kilowag etc being exceptions to this human durability rule
