Saying that "I Don't lead a LS or join one because i have a life" is why he isn't taking you seriously, or what he was judging it on.
The context of what you said, its sounds like you're saying "LoL anyone who runs a LS or joins a HNMLS has no life". Which is something only an ignorant child would say. because its classify multiple diverse people all in 1 little group.
Its also generally used by very gimp unintelligent people who use "Real life" as an excuse to remain mediocre. Tell you, For years of FFXI, I had a full time job, School, and a GF (I still have 2/3 of those!) and I learned the game and geared myself just fine. Real life has 0 to do with it.
If thats not what you meant to say, You just need to clarify, Cause i assume this could be a misunderstanding on his part.
--------------------
More on this Specific at hand topic, Is it purposefully suppose to be about level 75 colibri parties? Cause so much has changed since 75 anything about those kind of parties is obsolete and stupid information.
THF since 75 has gotten more Dual Wield, Much better gear (For instance, i Can sift comfortably @ ~20% Triple Attack rate outside of Abyssea, With capped Haste). We have Critical hit Damage+ Job traits and gear, making Evisceration more powerful a tool than it used to be, etc.
A lot has changed. Not the least of which is much higher DEX/AGI improving our SA and TA numbers.
Now, For my opinion on THF. Its a wonderful job, but seriously cram a sock in it if you think it doesn't need fixing. This job needs so many things done. Only people who think the job is find is jealous and or/butthurt people who think Treasure hunter is so awesomely over-the-top broken. Its not that great. sure its useful for just about everything, But its not an excuse to screw THFs out of other meaningful abilities.
First off, 80% of THF abilities are completely useless in Solo/Duo groups where THF is tank. SA, TA, Hide, Flee, Mug, Steal, Despoil, Collab, Conspirator, Accomp, and in most cases these days, Even Feint.
Despoil/Steal/Mug are completely useless anyway outside of making some small bits of gil, And even so they're all worthless on NMs in abyssea, as for some reason SE thought it would be cool to give THF another Steal ability that doesn't work on things you might actually want to debuff, NMs.
THF needs to be looked at and Re-evaluated. I've given my ideas in other threads, THF is a wonderful job, But it desperately needs a boost in the DD department. It doesn't need to be pushed to the point its out-damaging Ukon WARs point for point, But pushing it to where the gap is at least not as huge as it is now would be nice.
THF was meant to be a DD and a TH, SA and TA didn't happen on accident. I dont ask for much, But maybe some boosts that actually put THF on top of the Critical Hit Rate/DMG Food-chain again.
MNK got Impetus, Which is JA that should have went straight to THF. Acc, Critical Hit Rate? Sounds THF to me. Acc+Subtle Blow? THF doesnt even get native Subtle Blow. FK Conspirator I'm sorry.
On to my Suggestions
---------------------------------------------
*Job Traits
-Give THF Critical Attack Bonus sooner and more than everyone else. They should be unique in something, Critical hit Rate and Damage should be it.
-Crit. Atk. Bonus I
Level 15 THF
-Crit. Atk. bonus II
lv 35 THF
-Crit. Atk. Bonus III
lv 55 THF
-Crit Atk. Bonus IV
lv 75 THF
-Crit. atk. Bonus V
Lv. 85 THF
-Crit. Atk. Bonus VI
lv. 99 THF
*(Bonus being Starting @ +5, +3 Each Trait, total of +20% Critical hit Damage at level 99)
Also, Give THF the Same thing with Critical hit Rate. +3% Each level, Up to level V though, For a Total of +15% Critical Hit Rate. 10/30/50/70/90 levels.
This will help THF tremendously. I mentioned this before but I'll do it again:
Give us a "Restraint" Like Ability for sneak attack and Trick Attack. Make it for Each hit landed, It increases the DEX or AGI mod for Sneak Attack/Trick Attack by 0.5, for a Maximum of +50% (meaning 100 hits to cap potency).
For Fairness Sake, Give us this ability at 91+. It is rather beef,
THF doesn't need to become the best broken DD Ever, But giving it boosts like this will shorten the gap.
